Shamil Mamedov invested some money at $5\%$ simple interest and $\$2,000$ more than that amount at $6\%$. The interest for the year totaled $\$670$. How much was invested at each rate? Step 1: Read the problem, we are asked to find the amount invested on each rate. Step 2 : Assign the variable. Then organize the information in the table. Let $x = $ amount invested at $5\%$ interest rate. Then, $x + 2000 = $ amount invested at $6\%$ interest rate $ \begin{array}{|c|c|c|c|c|c|} \hline & \rm{Principal} & \cdot & \text{Interest Rate} & = & \rm{Interest} \\ \hline 5 \% & x & \cdot & 0.05 & = & 0.05x \\ \hline 6 \% & x + 2000 & \cdot & 0.06 & = & 0.06(x + 2000) \\ \hline \end{array} $ The total interest earned is equal to the sum of the interests at each rate. Step 3: Write an equation from the last column of the table $0.05x + 0.06(x + 2...

int (4x - 2/(2x+3)^2)dx To solve, express it as difference of two integrals. = int 4x dx - int 2/(2x+3)^2dx Then, apply negative exponent rule a^(-m)=1/a^m . = int 4xdx - int 2(2x+3)^(-2)dx For the second integral, apply the u-substitution method. u = 2x + 3 du = 2dx Expressing the second integral in terms of u variable, it becomes: =int 4xdx - int (2x+3)^(-2) * 2dx =int 4xdx - int u^(-2) du For both integrals, apply the formula int x^ndx= x^(n+1)/(n+1)+C . = (4x^2)/2 - u^(-1)/(-1) + C =2x^2 + u^(-1) + C = 2x^2 + 1/u + C And, substitute back u = 2x + 3 =2x^2+1/(2x+3)+C Therefore, int (4x - 2/(2x+3)^2)dx=2x^2+1/(2x+3)+C .

Plants take in oxygen constantly during a process called respiration; they take in oxygen to derive energy from their food and produce carbon dioxide as a waste product. All living things use this process for energy. A major difference between plants and other living things, however, is the process of photosynthesis. Photosynthesis is the process of a plant taking in sunlight as an energy source (e.g., food source). During photosynthesis, a plant takes in carbon dioxide and releases oxygen as a waste product. Photosynthesis only happens in sunlight, or during the day. Plants give out significantly more oxygen in sunlight, or during the day, than they take in. At night, however, they don't photosynthesize; they only respire. This means that at night, plants take in oxygen but don't produce any. https://indianapublicmedia.org/amomentofscience/sleeping-with-plants.php https://www.bbc.co.uk/bitesize/guides/zpwmxnb/revision/3

Doris Lessing's story "Through the Tunnel" can be understood as a coming-of-age story.  Jerry and his mother are on vacation together, and Jerry is a typical, young boy.  He loves his mother, but he also wants to gain some independence from her.  He wants to test himself and see what he is capable of doing without a parent hovering right over him.  Readers realize much of this about Jerry from the first paragraph.  Jerry sees a rugged looking beach off in the distance.  It has some some rocks and is free from the crowd of vacationers, and Jerry wants to go explore it. However, he also feels badly about leaving his mother.   Contrition sent him running after her. And yet, as he ran, he looked back over his shoulder at the wild bay; and all morning, as he played on the safe beach, he was thinking of it. The next day, Jerry gathers up the courage to go to the other beach.  He is proud of himself, yet he does feel a bit lonely and maybe even a bit guilty at leaving his mother...

Tim O'Brien's short story "Where Have You Gone, Charming Billy?" is the tale of Private First Class Paul Berlin's first night of the Vietnam War as he and his platoon march through the countryside toward the coast. The two recurring themes in the story are Paul's fear and the death of fellow soldier, Billy Boy Watkins, who died of a heart attack that afternoon. The platoon marches silently, trying to avoid the notice of enemy forces. Paul is therefore left alone with his thoughts in the dark, humid night—thoughts he is strenuously trying to avoid: He was pretending he was not in the war, pretending he had not watched Billy Boy Watkins die of a heart attack that afternoon. . . . In the dark, with his eyes pinched shut, he pretended. The men move single-file through the night without speaking, passing rice paddies, villages, and a graveyard. Paul follows obediently, though feelings of isolation persist. The soldiers were quiet and hidden and faraway-seeming in a...

The answer to this is “absolutely not.”  A constitution is just a piece of paper.  It can only be enforced on the government if the people are willing to do so.  This means the government does not have to obey the constitution unless the people force it to do so. A constitution sets the rules that a government is supposed to follow.  However, a government cannot be coerced by outside forces.  Only the government has the legitimate right to engage in violence in a given society.  There is no force higher than the government that can physically compel it to act in a certain way.  This means that there is no entity that can force the government to obey its constitution.  As an example of this, we can say that there was a long time when the US government did not obey some parts of its constitution.  The Constitution of the US (specifically, the 14th Amendment) says that all Americans have to enjoy the equal protection of the law.  However, African Americans and other people of color were n...

Jane's rebellion takes place within the context of the patriarchal society that oppresses her. The room with the yellow wallpaper is symbolic of her imprisonment within the system set up by her husband, a doctor, and her brother, who is also a doctor. Trapped by the system they have set up for her, which is intended to be coddling but is also infantilizing, she sinks deeper and deeper into depression. Her husband's treatment of her is representative of the male medical establishment of the time, in which women's complaints, which often arose out of boredom (for wealthy women, who also had servants), were treated with a debilitating "rest cure."  Jane's rebellion consists only of peeling the wallpaper off her walls, which is, of course, not a rebellion at all. To fully resist the patriarchy of the time would have required her to leave the room with the yellow wallpaper. She would have had to escape from the infantilizing care of the men around her and to enter ...

Acid rain is rain that has a slightly more acidic pH level than normal.  Pure water has a pH level of 7.  Rain is generally slightly acidic to begin with, so "acid rain" is rain that tends to have a pH of 5.0 - 5.5.  The acid rain itself can be created through a combination of natural and man-made sources.  For example, volcanic eruptions give off elements that help to produce acid rain.  Human sources come from car exhausts and various fossil fuel burning activities.   Both of the above natural and man-made sources of acid rain are not evenly distributed across the globe.  Population densities vary across continent to continent.  Additionally, natural soil compositions differ as well.  Lastly, prevailing winds can carry acid rain and its components far away from their source regions.  All of those reasons combined explain why acid rain is not evenly distributed across the globe.  In the United States for example, acid rain tends to occur most in the Northeastern United State...

To understand this, we must first provide definitions for "disaster" and "hazard" in order to differentiate between the two. According to Merriam-Webster, there are a few definitions each for disaster and hazard; however, we will use the definitions that relate to our discussion. Disaster is “a sudden calamitous event bringing great damage, loss, or destruction,” whereas hazard is “a source of danger.”  A natural hazard would be a theoretical natural source of danger—something that has the potential to cause harm. A natural disaster, by contrast, would be the result of a natural hazard, should that hazard wreak havoc and destruction on land, communities, resources, etc. For example, Hurricane Harvey was a natural hazard that became a natural disaster once it made landfall and wreaked destruction.  https://cnx.org/contents/ZFLM8Ssk@1/The-difference-between-natural

During a solar eclipse, the Moon is in between the Earth and the Sun, but much, much closer to the Earth than the Sun.The precise distance would depend upon where the Earth is in its orbit; at perihelion the Earth is about 146 million kilometers from the Sun, while at aphelion the Earth is about 152 million kilometers from the Sun. The average is precisely one AU, or about 149.6 million kilometers.Then, it depends where the Moon is in its orbit around the Earth. At perigee the Moon is about 363,000 kilometers from the Earth; at apogee it is about 407,000 kilometers from the Earth. On average, it is about 384,000 kilometers away.As you can see, the distance from the Moon to the Sun really doesn't depend all that much on where the Moon is relative to the Earth; it depends almost entirely on where the Earth is relative to the Sun. In this sense, the "during a solar eclipse" part is kind of redundant; even during a lunar eclipse the Moon would only be about 800,000 kilometers...

"Greed" is present in these two works not so much in the conventional sense of avarice for money or possessions, as in the valuing of the material life over the spiritual one. Ivan Ilyich, though a man without glaring faults of any sort, has lived in the normal way people do, for work and for the support of his family and the ordinary things of earthly life. So have his wife and daughter. When he becomes ill, it's as if this is the first time he realizes that he is vulnerable and that earthly life will come to an end. His wife and daughter still don't sense that basic truth, and seem to have little empathy, just wanting to go on, uninterrupted, with their own material concerns. When he comes back from the doctor and tries to tell them what he has learned about his illness, they are unconcerned, more interested in going out shopping than in listening to him. The only person who does have a degree of empathy is Ilyich's footman, Gerasim. We're told that Gerasim ...

The direct context of the quote is that the retired Woodifield, who has had a stroke, is only allowed out to visit the City--central London--once a week by his wife and daughters. They can't imagine what he does there, but then the narrator explains that "we cling to our last pleasures as the tree clings to its last leaves." A tree clinging to its last leaves is an image of a tree near to death. This statement implies that Woodifield too is nearing death. He is an older man, and it does give him pleasure to get out and visit an old friend, as well as smoke a cigar. By more than simply a reference to Woodifield, it sets the tone for a very bleak story which primarily concerns death: the death of Woodifield and the boss's sons in World War I (Woodifield has come to report that his daughters saw both graves). It provides a context and becomes a metaphor for the disturbing high point of the story, in which the boss deals with his grief over his dead son by torturing a f...

cos(pi n)={(1 if n=2k-1),(-1 if n=2k):}, k in ZZ i.e. it is equal to 1 for odd n and -1 for even n. Therefore, we can break this into two cases. n=2k-1 (n is odd) lim_(n to infty)a_n=lim_(n to infty)1/n^2=1/infty^2=1/infty=0 n=2k (n is even) lim_(n to infty)a_n=lim_(n to infty)-1/n^2=-1/infty^2=-1/infty=0 Since the limit is the same in both cases, the sequence is convergent and its limit is equal to zero. Image below shows first 15 terms of the sequence. We can see that the odd-numbered terms are negative, while the even-numbered terms are positive, but they are both approaching the x-axis implying convergence to zero.

Paul Kalanithi’s moving memoir When Breath Becomes Air, which Kalanithi wrote while dying of cancer in his thirties, is peppered with references to and quotes from other works of literature. Kalanithi, who was trained as a neurosurgeon, earned degrees in literature and philosophy at Stanford and Cambridge before enrolling in medical school at Yale. His lifelong love of reading was encouraged from an early age by his mother, who gave him books recommended for students planning to take the SATs. Although Kalanithi eventually decided to seek answers to his questions about the meaning of life and death in science and medicine, his memoir shows that his earlier passions remained important touchstones for him. The title itself is a reference to “Caelica 83,” a poem by Elizabethan poet Baron Brooke Fulke Greville. Kalanithi also begins each section of the book with an epigraph, quoting from T. S. Eliot’s poem “Whispers of Immortality,” the King James Bible, and Montaigne’s essay “That to Stud...

John Proctor makes it clear that he is not a fan of Reverend Parris and believes that he is a superficial man, who does not possess the light of God. In act 1, John Proctor admits to Thomas Putnam that he does not appreciate the fact that Reverend Parris only preaches on hellfire and damnation. He tells Reverend Parris, "Take it to heart, Mr. Parris. There are many others who stay away from church these days because you hardly ever mention God anymore" (Miller, 29). Rebecca Nurse even agrees with John's assessment of Reverend Parris's preaching and says that there are many citizens who refuse to bring their children to church for that reason. In addition to preaching solely on hellfire and God's wrath, Proctor is also tired of Parris's greedy personality. Proctor views Reverend Parris with contempt for demanding a deed to his house and insisting on having golden candlesticks at the altar. Overall, John Proctor and many other citizens are tired of listening to ...

Cleopatra was a member of the Ptolemaic Dynasty.  Family members and ancestors in the Ptolemaic Dynasty had come from Macedonia on the Greek Peninsula.  Ancient Macedonians had expanded from today's Greece into other regions.  Alexander the Great had invaded Egypt, and from this the Ptolemaic Dynasty had come into power through his general.  Cleopatra was descended from Alexander the Great.  She was of Greek ancestry through him.  Members of the Ptolemaic Dynasty continued to speak Greek rather than Egyptian.  Cleopatra, by contrast, learned to speak Egyptian.  Her name was of Greek origin. Upon the death of her father, Cleopatra became a joint monarch with her younger brother.  In the culture of the Ptolemaic Dynasty, female rulers were considered secondary to male rulers in the case of a joint monarchy.  Cleopatra challenged this when she tried to militarily overthrow her brother.  

This is an interesting question. Most of the time, Isabel and America are compared to each other instead of contrasted from each other. A simple difference is that America is a country and Isabel is a person, but that is an incredibly simple contrast and not likely what your teacher wants to hear. One difference is that Isabel starts the story as a free slave, but America is not free from British rule. The country hasn't declared independence yet. The story begins in May of 1776. While America might be getting ready to declare independence from Britain, it has not happened yet; however, Isabel begins the story having recently been set free. She is forced back into slavery, and soon after, America becomes its own free country. This is a sort of role reversal that occurs in the story. I would say that another key difference is that Isabel is willing to work with the British in order to become free again. That is why she tries to escape the Lockton household by going to the British mi...

Anthony certainly cheats on Gloria. During the war, when he was stationed in South Carolina, he had an affair with a local girl by the name of Dorothy Raycroft. It's not hard to see why Anthony succumbs to temptation. Dorothy is just so incredibly real, certainly not the kind of woman he's used to meeting in his rarefied social world. And she's absolutely nothing like Gloria, the shallow, superficial, would-be movie star going crazy over the prospect of hitting thirty. Dorothy may not be as beautiful or as sophisticated as Gloria, but she has a wonderfully grounded air about her. In some ways, Anthony envies her. He's spent the whole of his pampered existence trying desperately to find a purpose in life. Yet here is someone with her feet firmly planted on terra firma. Unlike Anthony, however, Gloria does at least grow as a character throughout the story. And crucially, she has a conscience. She abjures her youthful nihilism to embrace a weird religion called Bilphism. W...

Shakespeare characterizes the three Weird Sisters by allowing them to establish the mood of the play in the very first scene. Right away, the dark and ominous mood is set with thunder and lightning and these three creepy women making plans for what they are going to do after the battle's over; these plans sound somewhat nefarious. During their conversation, they also speak to their familiar animal spirits—"Graymalkin" and "Paddock"—a very strange and off-putting behavior. In addition to interacting with these spirits, the sisters' speech pattern helps to establish their characterization as well. They speak in rhyming couplets, a pattern that sounds hypnotic and spell-like: "witchy" if you will. They also speak in a particular rhythm called trochaic tetrameter. This means that there are four (tetra-) feet per line and each foot is called a trochee (which is two syllables: one stressed syllable followed by one unstressed). Most of the other character...

If there is one characteristic that defines all of humanity, it is our eternal limitation. From the moment we are born, each of us is bound to die. Given the stark realisation that none can escape death and that we are all subject to the chaos of a seemingly indifferent universe, it would be easy to assume a nihilistic and hopeless mindset and allow ourselves to simply fade into oblivion. After all, if existence is without meaning, why should we bother to do anything? The trouble with nihilism though is that it most often leads people down dark, destructive and frequently suicidal paths. Only a fool would try to deny that our world is beset by great suffering, but the reason that Do Not Go Gentle holds such power is that it strikes directly at the core of what it means to exist. True meaning and purpose are not to be found in the pursuit of momentary happiness, but in facing situations which seem impossibly grim and discovering the strength to soldier on regardless. The poem expresses ...

In Shelagh Delaney's play—and later, film—A Taste of Honey, a teenager named Jo finds herself struggling with her roles and responsibilities in life. She wants to leave school and is frustrated with the impoverished life her mother has set for her. She briefly dates a Black sailor and becomes pregnant by him. During her pregnancy, Jo meets Geoff and the two forge a strange but mutually fulfilling relationship. The two come to fulfill some surrogate parental roles for one another, sharing in advice, consolation, and housekeeping. Geoff is a young, effeminate man who we can understand based on implicit media "coding" of the time to have been gay. Though his sexuality is never mentioned outright, Geoff as presented as having many feminine behaviors, which were widely conflated with homosexuality in men at the time. (You may notice that this persists in Western culture today, where a man's sexuality may be questioned on the basis of his doing or enjoying something commonl...

Instead of approaching this from the perspective of "evils," let's look more generally at what was occurring in 1775 in England and France. England was about to experience the American Revolution. The American colonies were important to Britain's economy, but the colonists started the revolution with the aim to be free of British rule, partly due to being taxed heavily by the British government. France was at peace, but there was great unrest, and the French Revolution (1789) was on the horizon. France helped the American colonists during the American Revolution and was in debt. Cultural changes, partly brought on by the American Revolution, influenced thinking against the monarchy, as did the rule of Louis XVI. Louis XVI became king in 1774 and was considered tyrannical. Inflation was high, including, famously, the cost of bread. Queen Marie Antoinette's famous supposed, but not historically accurate, line upon hearing that the people couldn't afford bread wa...

The government had a significant role, as it tended to follow a laissez-faire attitude toward business. There were few regulations, which worked to encourage business owners to try new things and to expand their businesses. The government also offered land either for free or at lower prices in the West. This also encouraged people to move to the West. Businesses expanded to meet the growing demand in the western regions. The government also helped businesses grow by supporting many internal improvement projects. Roads and canals were built. This helped people move westward. The support for the building of the transcontinental railroad also helped the western regions grow. It was easier for people to travel to the West. Products could also be shipped faster to the West than in the past. The railroads were also responsible for the growth of industries and the rise of big business. The building of railroads encouraged Westward Expansion. It was easier for people to move to the West. These...

It's Act III Scene II, and the conspirators have finally carried out their plan and brutally assassinated Julius Caesar. The late dictator was hugely popular among the common people of Rome. When they find out what happened to their hero, the people are fearful, angry and confused. They need to be reassured; they need to be placated. Otherwise, Rome's new rulers will have chaos and disorder on their hands. So up steps Brutus, the most senior conspirator, to make a speech which he hopes will persuade the masses why getting rid of Caesar was the right thing to do. Ethos- This is a rhetorical device which seeks to make an appeal to its audience on ethical grounds. The first thing to notice is that Brutus' speech is in prose, not the more elevated style of blank verse. In speaking this way, Brutus is trying to show the people that he's one of them, an ordinary person who just wants what's best for Rome: Believe me for mine honor, and have respect to mine honor that you ...

"The Tree of Song" seems to be addressed to a person of great influence to the speaker. The speaker says plainly, quietly, and with a tone almost of awe that this person in question has stripped away all that is superfluous about the speaker and revealed her very core, "the tree of my song." Below is a line-by-line take on the poem. "I sang my songs for the rest, / For you I am still." The speaker's "songs" or "leaves" seem to be extraneous to her existence. They are nice, and she produces them (perhaps the way a poet produces poems?), yet they are not essential to her being. They are easy to give away. So, the speaker sings her songs for "the rest," for other people, but for the subject of the poem, she has more reverence and interest: "I am still." "The tree of my song is bare / On its shining hill." This somewhat plays off the expression "to bare one's soul," which means to open up and ...

Curzon is a young male slave in the book Chains. His owner is Bellingham, but Curzon enjoys a fair amount of freedom as compared to Isabel, who is worked to the bone by Madam Lockton. Curzon is also an extremely well educated slave when it comes to knowing about politics and the war. This works well for him since he spies for the Patriots against the Loyalists. He even recruits other slaves like Isabel to help him spy. Curzon is also a passionate American Patriot. He believes in the revolutionary cause to his core. He even is unafraid to publicly call himself an American soldier. Curzon is also a devoted and caring friend to Isabel. He is one of the first characters to show her any kindness, when he shows her the Tea Water Pump and takes her to the Lockton's household. He also acquires food for the two of them, but he declares he isn't hungry when he sees how starved Isabel is. Curzon is also the person that enlists Lady Seymour's help for Isabel after her branding. His kin...

In Flowers for Algernon, a novel by Daniel Keyes, Charlie Gordon is a mentally challenged man who undergoes a scientific experiment to make him more intelligent. Prior to the operation, he works at a factory. The men in the factory treat him like a joke and use him for their entertainment. For example, they laugh when he makes mistakes. They take him out drinking in order to laugh at his behavior, and when problems arise, they abandon him. Charlie doesn't talk much about his landlady prior to the changes that occur in him as a result of the operation, but he mentions that she seems frightened of him as he starts to progress in intelligence.  Before the operation, Charlie assumed that the people at the factory who were making fun of him were his friends and that they were not laughing at him, but with him. Once he begins to progress, he realizes that they are not being friendly, but cruel. He feels ashamed that he has been an object of ridicule without realizing it.  "Mrs. Flyn...

An extension of Realism, Naturalism is a literary movement that claims to portray life exactly as it is. Naturalists tend to dissect human behavior with absolute objectivity. Relying heavily upon certain areas of psychology and sociology, this movement is also influenced by Darwinian theories of survival of the fittest as well as a certain determinism. Thus, human beings are subject to laws of nature, just as animals are, and in Crane's and London's writing, it is an essentially indifferent universe in which characters exist. Stephen Crane writes in a style that places the reader in the created experience so that this reader is affected by events at the same time as the characters themselves. In this way, the reader senses the deterministic factors of the fictional universe simultaneously with the characters, and the impact is powerful. Poetry Often there is an indifferent universe, as in this short poem of Crane's:    A man said to the universe: "Sir I exist!" ...

Because this topic is so broad, there are infinite directions that you can take it! One interesting topic would be justifications of war. This could be a discussion of what constitutes a just war; you could juxtapose that with what makes a war unjust. You could include examples by finding a war that you think was justified (example: World War II) and then explain why it was justified (example: because it ended a genocide). Then compare it to a war that you think is unjustified and discuss what the characteristics are that make a war justifiable or not. Another interesting topic would be comparing two wars that happened around the same time such as the American Revolution and the French Revolution. You could investigate the ways that the revolutionaries in France developed their ideologies considering the ideologies of the American revolutionaries. The same would work for many different couplings of wars. Similarly, it might be interesting to discuss the stages of a revolution (normal, ...

There is a strong connection between a country's level of poverty and the strength of its overall economy. When poverty levels in a particular nation are high, consumers usually spend less money. This can hurt the manufacturing and commercial economies, which in turn leads to more poverty as fewer people are hired, pay stagnates, and the GDP of a country falls. When poverty rates decline, however, there usually is a boost in the economy. As consumers spend more, more jobs are needed, which helps pull more people out of poverty. As you can see, this circle works in both directions. Therefore, it is not always clear what the causal factor is. Determining if it is the levels of poverty and wealth or the direction of the overall economy that drives the relationship is a large part of the study of macro-economics. It is also good to remember that high poverty levels seldom affect everyone in a country. There almost always remains a small subset of the population that holds on to a degre...

First calculate how submerged the block is when in equilibrium. Let the up direction be negative and the down direction be positive. F_b=F_g+F rho_w*V_d*g=rho*V*g+F, rho=S_g*rho_w rho_w(1^2*x)g=S_g*rho_w(1^3)g+2000 ,Where x=the distance from the surface to the bottom of the block (here is why I have the downward direction as positive). Then solve for x: x=S_g+2000/(rho_w*g)=0.6+2000/(1000*10)=0.8 meters Now to calculate the velocity, at a height h, we must neglect the drag force then use the work kinetic energy theorem. W=Delta*K int_0.8^h F(x) *dx=1/2m*v^2 The initial velocity is zero. F(x) is the net force on the block after it is released as a function of the distance submerged. We are only considering when h  (2/m)int_0.8^h (F_g-F_b(x)) *dx=v^2 (2/(S_g*rho_w*1^3))int_0.8^h (S_g*rho_w*g-rho_w*x*g) *dx=v^2 2g int_0.8^h dx -(2g)/(S_g) int_0.8^h x dx=v^2 2g(h-0.8)-g/(S_g)(h^2-0.8^2)=v^2 (2g(h-0.8)-(g)/(S_g)(h^2-0.8^2))^(1/2)=v(h)  Here is velocity as a function of height where h The gr...

The answer to this question can be found in Chapter Five of Dog Whistle Politics, which actually deals more with the racism in the Clinton and George W. Bush presidencies. Lopez presents the elder George Bush as the product of moderate Northeastern conservative Republicans, who had generally eschewed race-baiting as a political tactic. But Bush was also faced with the possibility of losing the 1988 election to Michael Dukakis, and his chief campaign advisor, Lee Atwater persuaded him that he had "plotted a racial route to victory," and the genteel Bush accepted his advice.  Lopez focuses on the Bush campaign's notorious Willie Horton advertisement as the means by which race became a pivotal feature of the election. Horton, imprisoned for murder, broke into a house, stabbed a man, and raped his partner while on furlough. Michael Dukakis had, while Massachusetts governor, vetoed a measure that would have denied furlough to convicted murderers, and Atwater played on this fac...

A simile is a comparison of two unlike things using the words like or as. The comparison tends to enhance the qualities of one of those things. Immediately after seeing Juliet at Capulet's party in Act I, Scene 5, Romeo compares her beauty (it is definitely her looks he is speaking of here because he has yet to meet her) to a precious jewel: It seems she hangs upon the cheek of nightAs a rich jewel in an Ethiop’s ear This comparison needs a bit of explanation because one might not understand what Romeo is speaking of. It was probably common in Renaissance Italy for men from Ethiopia to act as traders and to visit Italian cities. Romeo may have seen just such a man, or maybe read about them. These Ethiopians were often wealthy and would have adorned themselves in elaborate jewelry such as diamonds, emeralds or rubies.   Later, in Act II, Scene 2, Romeo once again uses a simile to describe Juliet. Here he may also be speaking of her personality and not just her beauty because he has ...

Prejudice is a negative opinion about a person or group of people that is not based on actual experience. Discrimination occurs when a person acts on their prejudice. The development of prejudice can occur in many different ways. Research has shown that individuals may develop prejudice as an attempt to build self-value when a person's self-esteem is threatened. This can occur in two ways. Individuals may ally themselves with a winning/ dominant group against a losing/ minority group. Alternatively, individuals may act on their prejudice on a person-to-person basis as an active manifestation of their belief that they are inherently better than the other person, discriminating to boost their self-esteem. When people experience an event that causes a drop in their self-esteem, they become more likely to act on prejudice in order to rebuild their self-esteem.

You need to find the component form of the vector v = , hence, you need to use the information provided. You need to evaluate the magnitude |v|, such that: |v| = sqrt(a^2+b^2) 3 = sqrt(a^2+b^2) The direction angle of the vector coincides to the direction angle of the vector u = ,such that: tan theta = b/a => tan theta = 5/12 => b/a = 5/12 => b = a*5/12 Replacing a*5/12 for b yields: 3 = sqrt(a^2+a^2*25/144)=> 3 = +-13a/12=> a = +-36/13 b = +-(36/13)*(5/12) b = +-15/13 Hence, evaluating the components of the vector v, yields or .

In this situation, we ignore the heat loss between the calorimeter and the environment. Then the heat that an unknown solid lost is the same as the heat that copper and water gain. Denote the heat capacity of the unknown solid as C, then the solid lost  Delta T_s * C Joules of heat, where Delta T_s = 95 - 35 = 60 (degrees). Denote the specific heat of copper as c_c = 0.386 J / (g * ^@C) and the specific heat of water as c_w = 4.186 J / (g * ^@C).  The temperature change for them is 35 - 10 = 25 (^@C), thus the heat gain is 25*(75*c_c + 130*c_w) =14294.5 (J). The final equation is  60 C =14294.5  and thus C =14294.5 / 60 approx238.242 (J)/ (^@C). This is the answer. The mass m_s of the solid would be used to find the specific heat of the solid. It is  c_s = C/m_s approx1.91 (J/(g*^@C)).   http://hyperphysics.phy-astr.gsu.edu/hbase/Tables/sphtt.html http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/spht.html

Answering this question requires one to determine in what way they personally interpret the world. These aren't hard sciences, so it has some room for subjectivity (hence why they are defined as perspectives). The functionalist perspective emphasizes the idea that society is made up of several social institutions working together. For example, family systems, school systems, business systems, and political systems are all cogs within a societal machine meant to promote social harmony. To approach social issues with this perspective is to deem some issues as "functional" or "dysfunctional." One potential problem when tackling social issues with the functionalist perspective is that this perspective is predicated on the idea that these social institutions are constructed for good, and it may be too lenient on possible malice amongst the institutions themselves because of a generalized hopeful outlook keen on maintaining the status quo. The symbolic interactionist ...

This question is referring to the aphorisms Franklin published under the pseudonym "Poor Richard." The first aphorism is "the wise man draws more advantage from his enemies than the fool from his friends." This aphorism essentially means that wise men pay attention to what their enemies say about them and how they act against them. Your enemies are looking for your weaknesses and shortcomings. They have no interest in portraying you in a positive light. Your friends might flatter you, and, while it is important to have friends, they cannot really teach you anything. Another aphorism is "when befriended, remember it; when you befriend, forget it." In this context, "friend" seems to mean something like "benefactor" rather than "companion." Essentially, when someone does something for you, remember it, so you can reciprocate. When you do something good for someone else, do not expect anything in return. Do good things for people,...

In chapter 7 of Ready Player One, Wade is on the planet Ludus in the OASIS. He must find the Tomb of Horrors, which is part of Dungeons and Dragons, to look for the Copper Key. Wade knows that he may face the evil demi-lich once he is inside the Tomb of Horrors. He defines a lich as an "undead creature." It could be a wizard or king that "uses dark magic" to connect his intellect to his own dead body. Since they are often present in video games and fantasy books, Wade is familiar with liches. He believes that he must acquire magical items in order to stand a chance against the creature. As he works his way through the chambers, he fortunately collects some of these magical items. When Wade reaches the Pillared Throne Room, he sees the "demi-lich Acererak." It turns out that Wade must battle the creature by playing a 1980s video game called Joust.

Thomas' poem, "Do Not Go Gentle into that Good Night," does indeed use imagery to illuminate the connection of human beings and nature, but it is also a study in the existential difference between humans and the rest of the world. The comparison of death and night serves as the central metaphor, but it also alludes to the shortness of non-human beings whose lives last only hours or days or only a few years. While the metaphors tie "Good men" to the natural world, his images also explore the internal "rage" of beings who can anticipate their own deaths and regret the wasted moments. All animals resist death but only humans can see it coming. The second line in the first five stanzas all explore regret and failure: "Because their words had forked no lightning," "Their frail deeds might have danced," etc. Animals do not regret the lost moments or failed endeavors. Humans are simultaneously in the natural world and removed from it. W...

Find the integral $\int x^3 (2 + x^4)^5 dx$, by making $u = 2 + x^4$ If $u = 2 + x^4$, then $du = 4x^3 dx$, so $\displaystyle x^3 dx = \frac{1}{4} du$. And $ \begin{equation} \begin{aligned} \int x^3 (2 + x^4)^5 dx =& \int u ^5 \frac{du}{4} \\ \\ \int x^3 (2 + x^4)^5 dx =& \frac{1}{4} \int u^5 du \\ \\ \int x^3 (2 + x^4)^5 dx =& \frac{1}{4} \cdot \frac{u^{5 + 1}}{5 + 1} + C \\ \\ \int x^3 (2 + x^4)^5 dx =& \frac{1}{4} \cdot \frac{u^6}{6} + C \\ \\ \int x^3 (2 + x^4)^5 dx =& \frac{u^6}{24} + C \\ \\ \int x^3 (2 + x^4)^5 dx =& \frac{(2 + x^4)^6}{24} + C \end{aligned} \end{equation} $

Methylmercury, also called quicksilver, is a highly toxic form of mercury. Methylmercury is produced by microbes living in wet environments like bogs, the ocean, and rivers. Animals which live in these environments may ingest methylmercury, and as it is bioaccumulative, this becomes more and more dangerous the higher up on the food chain an organism is. Humans most often ingest methylmercury through seafoods like tuna fish.  When humans ingest too much methylmercury, they may experience heart attack, tremors, loss of vision or hearing, or other forms of central nervous system damage. In the fetus, methylmercury poisoning can significantly affect development and cause lifelong blindness, deafness, microcephaly, and mental and physical impairments.  Methylmercury has a half life of about 50 days in the human body, but it is much easier for this substance to accumulate in the small bodies of children and fetuses. For people of all ages, doctors recommend limiting the amount of large fish ...

Dualities in A Tale of Two Cities serve to point to the similarities of internal problems in England and France as well as developing themes and characterization. From the opening of this classic novel on, there are presentations of dualities. With thesis and antithesis, Charles Dickens points to the similarities between England and France in the opening chapter, as he compares the king of England with the king of France while the Woodman, symbolic of the guillotine, and the Farmer, symbolic of the peasants who stormed the Bastille, work unheeded. Some characters act as dualities, as well, as Dickens often places an English character in contrast to a French one: Sydney Carton -- Charles Darnay (Evremonde) The brilliant, but dissipated, Carton sees in noble Darnay what he could have been, and he is inspired by his idealized love for Lucie Manette to redeem himself through self-sacrifice. "For you and for any dear to you, I would do anything," he declares to Lucie in Chapter 13...

Gieve Patel (born 1940) is an Indian poet and artist who was born in Mumbai, where he settled after obtaining his M.D. and where he works as a general practitioner. Patel is a member of the "Green Movement," a group of writers concerned with protecting the environment. In an interview, Patal described the genesis of the poem: “I was twenty and studying medicine at Grant Medical College (Nagpada). One morning when I went to the college compound, I saw a beautiful tree uprooted by the storm. I sat down and wrote the poem.” The first theme of the poem is the unity of the tree with the earth. The tree is portrayed as gradually emerging from the earth and drawing strength from it. When damaged, the tree can retreat back to its roots, still embedded in the earth, and grow again. It is only if the tree is ripped out of the earth entirely and its roots exposed that it will die. This leads to a more metaphorical symbolic theme, namely that all life is connected to the earth and that w...
