Hannah BeckMrs. StiffHonors English 101/12/17 Hysteria is known to have crushed endless networks, and in incident it had gone over the city of Salem; an expected 200 individuals were blamed for black magic and more than 20 individuals were murdered because of the widespread wrath all through the city. The Crucible composed by Arthur Miller portrays the untold truth of Salem, Massachusetts, and the commitment for an in simply strict society during the shocking occasions of the witch preliminaries. The term madness by and large alludes to as (MPI), mass psychogenic sickness, yet this can be similarly as sociological just as a mental wonder that happens in practically all inclusive characteristics in us as people. Many have looked to Salem for instance of mania, in which they had encountered a monstrous aggregate frenzy that moved through the city, as their chase for witches turned into an incomprehensibly important issue. For what reason did a kept Puritan culture rapidly for the time being transform into the hustle for finding, and making allegations of witches? Well it is in our human instinct, us as people can rapidly accept nearly anything when we experience it firsthand, despite the fact that as ludicrous as it appears. We will compose a custom exposition test on Hannah Beck or then again any comparative theme explicitly for you Don't WasteYour Time Recruit WRITER Just 13.90/page As Arthur Miller says, Salem resembled investigating a petri dish, a treated balance with its chief moving powers got into quietness. One needed to think about what the human creative mind benefited from that could move neighbors and old companions rise for the time being as rages covertly twisted on the torment and the demolition of Christians (Miller, 3). In the Crucible, mania is most unmistakably found in the residents unreasonable acknowledgment of the young ladies manufactured cases of black magic. As a great many people in the city had encountered black magic firsthand their brains had revealed to them that it was to be sure occurring and for them to rapidly freeze in the situation of decisive. Presently returning to what Arthur Miller had stated, I accept that our minds are benefited from the unavoidable truth or passing. In a particular situation, where it was your life and notoriety on the line per state and your neighbors life on the line, okay either make a case to make your neighbor look liable, or would you not? Numerous individuals were blamed for black magic as a result of insanity, and as I said agitation is additionally mental sickness. I accept that their brains had continued advising them to escape the circumstance and for them to spare themselves, instead of keep themselves in the perilous frenzy of the preliminarie s.

Argument Essay Topics For Kids

Argument Essay Topics For KidsThere are a few argumentative essay topics for kids that can be taken in a grade school course or an honors one. They can also be used in grade school and high school, for students who are serious about their studies. They can serve as practice for the writing of high school papers, for the college application and thesis.Argumentative essay topics for kids should be different in style and content from that of the argumentative essays for adults. This is due to the fact that arguments made by adults should have some level of substance, while the child's arguments should be more personal and less analytical.For this reason, the way argumentative essays for kids are presented will differ from that of adult essays. Instead of outlining a thesis statement, argumentative essay topics for kids should be developing arguments. Arguments need to be made, based on examples alone. The only way to make an argument is by using examples.All arguments are based on argum ents. Arguments are different from theories or statements and they are all based on the same premise. That premise is that, there is something out there, and it's not true.Argument essay topics for kids should contain three types of examples. First, examples of fact, and two examples of statement. The first type is very important in these kinds of essays. This is because kids need to be shown what the problem is, and what they must do to fix it.Secondly, facts need to be introduced into the argument. Factual statements are needed to back up statements made in the argument. And finally, people need to be introduced into the argument as being individuals, rather than one isolated thing.Argument essay topics for kids can be presented in a number of ways.

Diabetes A Healthy Body - 1604 Words

In a healthy body, carbohydrates are broken down into glucose which is necessary to survive. Glucose is blood sugar and is used in more than one way throughout the body, for example providing fuel for the brain, providing energy for the body and essential to create proteins. The pancreas creates a hormone, insulin, which helps the body store glucose, when it is not being used, in the liver, muscles and fat cells, ready to be turned into energy as the body needs it. When somebody’s supply of insulin doesn’t have the ability to store glucose, it means that they have diabetes. Because the prospect of storing is no longer an option, glucose remains in the blood system, building up to severely high levels. Diabetes is all linked back to sugar.†¦show more content†¦Type 1 is also known as juvenile diabetes as it was far more common in children than Type 2. In more recent times, there is a higher percentage of children with Type 2 diabetes than Type 1. Type 2 diabetes is different in that the pancreas still produces insulin but certain elements diminish the ability to absorb and convert glucose. Type 2 diabetes is often treated with a combination of medications, a careful dieting and exercising balance as well as weight loss and careful attention to the levels of blood sugar. Type 1 diabetes is much more common in Northern European countries, and among people of Northern European descent. Type 2 diabetes is found in countries with higher obesity levels, for example the United States. One out of every three Americans is considered to be obese. Diabetes can affect the heart, eyes and kidneys and results in problems in the circulatory system- the blood system. Type 1 can also affect blood vessels and nerves. It can lead, if not managed properly, to blindness, heart disease, strokes and vascular disease which, in turn, leads to gangrene and the need for amputation. At the time of the Ice Age, diabetes was a huge advantage in humans. Although unbeknownst to those it affected, diabetes helped people survive the colder temperatures. Those without diabetes survived for a much shorter period of time, allowing diabetes to become more and more common. The build-up of blood sugar was the anti-freeze within the

Negative Effects Of The Columbian Exchange - 1498 Words

In 1492, Christopher Columbus sailed the ocean blue. This was the very first step in starting the Columbian exchange. The Columbian exchange was the process of the New World and the Old World transferring ideas, plants, animals, culture, human populations, and manufactured goods across the Atlantic Ocean throughout the 15th and the 16th century. Even though there were many positive results out of the exchange including the finding of the Americas, new plant and animal species, and the Europeans gaining more land to grow their Old-World crops, the overall effects were negative. The Columbian exchange was not as successful as it was made out to be because there were over ten major disease outbreaks in both the Old and New world, Europeans†¦show more content†¦Although there is very few examples of diseases spreading from the New World to the Old World, that does not mean they weren’t as devastating as the Old-World diseases. Syphilis is a New World disease that was fata l and had severe symptoms. They included genital ulcers, rashes, large tumors, severe pain, dementia, and eventual death. Over time, as the disease evolved, its symptoms changed, becoming more benign and less fatal (Nunn and Qian, p.4). There are two theories of the origins of syphilis is one being the â€Å"Columbian hypothesis† and the other being the â€Å"pre-Columbian hypothesis†. The Columbian hypothesis states that the disease-causing agent Treponema pallidum originated in the New World and was spread in 1493 by Christopher Columbus and his crew who acquired it from the native people of Hispaniola through sexual contact. When men joined the military campaign in Spain they would bring back prostitutes in their camp sites which would amplify the disease throughout Europe when they returned. The pre-Columbian hypothesis states that syphilis has always been in the Old World. since no accounts of the disease were made prior to the 1490s because it could not be differ entiated from other disease with similar symptoms, it was made to believe that it was always around just not classified yet.

Romeo and julietlove Free Essays

Romeo and Juliet written by William Shakespeare is one of the most famous love stories. Most people think it is Just about romantic love, but indeed it has many different forms of love that exists which is portrayed throughout the Shakespearian novel. The novel uses the main theme of love to push the story along and keep it going. We will write a custom essay sample on Romeo and juliet:love or any similar topic only for you Order Now Presented are variations of love including forbidden love, unrequited Love and blind love. This essay aims to analyse these three types of love chosen. Romeo and Juliet is a brilliant play about a young boy and girl, whom fall deeply in love with each other. Romeo is from the house of Montague, while Juliet is from the house of Capulet. Both families have been feuding with each other for a long time; however, despite the families feuding, Romeo and Juliet marry each other in secrecy. This is an example of forbidden love. In Romeo and Juliet the two main characters rush into love and it didn’t end up the way they planned it to. They see each other’s seen beauty and think they will live happily together, but things change throughout the tory that take a turn for the worst. Romeo gets banished from Verona making their love for each other hard making them sneak around to manage it. Juliet pretends to kill herself so Romeo would come back but Romeo goes back thinking Juliet actually killed herself, so he decides he must kill himself. Juliet wakes up and sees her love dead and decides if she cannot live with Romeo she will not live at all, and kills herself also. The first time Romeo sees Juliet he says, â€Å"Did my heart love till? / Forswear it sight! For I ne’er saw true beauty till this night† (1. 5). Romeo without hesitating decides that he is in love with Juliet now even though he has not spoken to her at all. Which brings us into unrequited love and the ‘one sided’ love between Romeo and Rosaline. You are never positive if someone really loves you or not. All you know is that you truly love them. That is what makes unrequited love difficult for people. In Romeo and Juliet, unrequited love is present whether it was apparent or implied, we don’t know. When we are introduced to the character Romeo, he is infatuated by Rosaline which he thought was love at first sight, but she happens to not be in love with him and plans to become a nun. Romeo is in love with Rosaline while Paris falls in love with Juliet which are the most obvious examples in Romeo and Juliet. Romeo’s apparent â€Å"love† for Juliet is no different than his love for Rosaline because Romeo is in love with the idea of being in love. Although, I do believe there is an unrequited love between Juliet and her parents. In Romeo and Juliet, love and hate are Just two emotions on the same side. Both emotions are intense emotions that as Benvolio says, get the â€Å"mad blood stirring† (3. 1. 4). When the hatred is going on between the Montagues and Capulets, it finally pushes Romeo and Juliet to their tragic deaths but which their parents thought they were doing right for their children. But if they’re Just two emotions on the same side, then can this kind of passionate love even exist without hate? romeo and juliet:love By victoriacoates How to cite Romeo and juliet:love, Papers

Leszek Swirski Essay Example

Leszek Swirski Essay I will investigate the change of velocity and acceleration of a laterally moving object attached by a string and pulley to a dropped object, when the mass of the dropped object is changed.MethodApparatus** Trolley* Piece of Card* Runway* Weights* 2 Light Gates* Weights* Pulley* Computer* LogIt 9000* Insight Timing* Appropriate cablesDiagramSet up procedureThis is how I will set up the experiment:1. Set up the apparatus as above, with Light gate A at 45 cm from where the centre of the piece of card (not trolley) will start to move from, and Light gate B at 45 cm further.2. Make sure that there is enough space between the pulley and light gate B for the piece of card to go through the light gate. If not, move the starting point of the trolley back, and the light gates accordingly.3. Plug Light gate A and Light gate B into the LogIt, and plug that into the computer.4. Start up Insight Timing on the computerThen I am ready to startFair TestI will make this a fair test by limiting the key factors:- Weight of trolley I will use the same trolley every time to ensure the same weight- Distance travelled I will keep this constant by releasing the weights from the same height and releasing the trolley form the same place every time. I will also not move the light gates- Friction/Air Resistance Unfortunately, these cannot be avoided, however they will be minimal due to the equipment used, and will be relatively constant as I will not change apparatus.SafetyThere is little safety to be considered. No harmful substances are being used, neither are flames or solvents. I will need to take precautions when increasing the dropping mass, and make sure that all the weights are securely fixed. The main point would be to stop/catch the accelerated trolley before it falls off, especially at higher speeds.Execution ProcedureThis is how I will execute the procedure1. The starting point should be the centre of the piece of card. I will have 10g as the dropping weight2. I will start r ecording on Insight Timing, and let the weight drop, making the trolley and, more importantly, the piece of card move.3. I will make sure someone catches the trolley before it falls off (see safety)4. I will stop insight timing and move the trolley back to the start position5. I will then add another 10g to the weight and repeat from 2. until I have measure the velocity at a mass of 100g.I will repeat this procedure two more times, so that I have 3 repeatsTheoryThere are three points to be considered in the theory. The first is how the mass should affect the velocity. The second is how the height should affect the velocity. The third is how the mass will affect the acceleration.First let me discuss the first point. This test is based on converting gravitational potential energy into kinetic energy.Gravitational potential energy (g.p.e.) is mgh, and kinetic energy (k.e.) is 1/2mv2.If we consider the mass of the trolley to be m1, and the dropping mass to be m2, this gives us g.p.e. as m2gh, as only the dropping weight has g.p.e. The letter g is the gravitational constant, and is approximated as 9.81. The letter h is the height. Equally, k.e. is 1/2(m1+ m2)v2, as both the dropping mass and the trolley will move.By Law of Conservation of Energy, energy can neither be created nor can it be destroyed, however it can be converted from one form to another. Therefore, if the g.p.e. is not wasted in any other way (e.g. friction converting it into heat energy), it must all be converted into k.e.This means that g.p.e. = k.e., therefore:m2gh = 1/2(m1+ m2)v2If I didnt have to consider m1, this could be re-written as:v2 = 2m2ghm2This would mean that the m2s will cancel out, proving that the mass of an object has no effect on its falling speed (as confirmed by Galileo). This is not true, however, when there is a constant added to the denominator. This makes the formula:v2 = 2m2ghm1 + m2This does not allow for the masses to cancel out, therefore the velocity (of both) must dep end also on the falling mass.The second point to consider is the height. Due to the setup, the vertical drop will be converted into both vertical and horizontal movement. This means that the height can be represented on the horizontal as the movement of the trolley. Since the speed is measured as the average speed of the card as it moves, the starting point should be the centre of the piece of card.The two light gates are therefore at 45 cm and 90 cm. This means that in the formula, h will be 0.45 and 0.9 (as h is measured in metres).I should also consider the effect the height will have on the velocity. The formula is:v2 = 2m2ghm1 + m2Since the h is in the numerator, it must directly and positively influence the velocity, i.e. as it increases, so will the velocity.As for the third point, acceleration, a different formula is needed. In this instance, it is:v2 = v02 + 2axv0 is the starting velocity and v is the final velocity (at light gate B). a is the acceleration and x is the dist ance moved. In this case, as light gate B is 90 cm from the starting point, x = 0.9. Also, since the trolley is not moving at the start, v0 is 0As we want to know the acceleration and v0 is 0, this can be rearranged and simplified as:a = v22hSince we know v2 to be:2m2ghm1 + m2we can replace the v2 in the acceleration formula to conform. Also After some simplifying, this becomes:a = m2g I(m1 + m2)Therefore, as the mass increases, so will the acceleration.PredictionThere are really two predictions to be made. One is on the subject of velocity, the other on acceleration.For velocity, I predict that as the dropping mass will increase, so the velocity will also increase. I predict that there will be a linear relationship between v2 and m2, therefore, I predict that the relationship between v and m2 will have to be parabolic, on its side. I also predict that, due to the height being lower at light gate A than B, the velocity will be higher at B than A. I predict the graph to look like thi s:For acceleration, I predict that dropping mass will increase, so the acceleration will also increase. Since m2 is in both the numerator and denominator, I predict that the graph will be hyperbolic, on its side. This is because, as the m2s increase, the effect of the added m1 will decrease, almost to a point where it is relatively insignificant, as m2 is so large. This would mean that the m2s increase to a theoretical point where m1 is irrelevant, and they cancel out, making the acceleration stay the same, as g (9.81). This would make the graph hyperbolic with the asymptote as 9.81:A AnalysingResultsRepeat 1Repeat 2MassVelocity AVelocity BTimeAccelerationMassVelocity AVelocity BTimeAccelerationkgm/sm/ssm/s/skgm/sm/ssm/s/s0.000.000.000.000.000.000.000.000.000.000.010.270.381.350.080.010.270.381.360.080.020.450.650.800.260.020.470.670.770.250.030.580.830.620.400.030.600.860.610.430.040.690.960.520.520.040.701.000.520.590.050.771.030.470.540.050.761.120.470.770.060.841.170.430.760.06 0.801.210.440.910.070.911.190.400.690.070.911.320.401.040.080.971.380.371.100.080.971.410.371.190.091.011.470.361.300.091.021.460.361.220.101.021.480.351.290.101.111.530.341.23Repeat 3MassVelocity AVelocity BTimeAccelerationkgm/sm/ssm/s/s0.000.000.000.000.000.010.310.461.200.130.020.480.720.770.310.030.600.900.610.480.040.701.040.530.650.050.781.150.480.770.060.841.230.440.880.070.911.370.411.110.080.961.420.391.170.091.021.500.371.310.101.071.590.351.49From these results I can work out an average set of results:MassVelocity AVelocity BTimeAccelerationkgm/sm/ssm/s/s0.000.000.000.000.000.010.280.411.300.100.020.470.680.780.270.030.590.860.610.440.040.701.000.520.580.050.771.100.470.690.060.831.200.440.850.070.911.290.400.950.080.971.400.381.150.091.021.480.361.280.101.071.530.351.34AnalysisThere are several pieces of information that can be extracted from the above table. The first two are the changes in Velocity at points A and B when the mass increases. The second is the change in acceleration as the mass increases. Also these values can be compared to the theoretical to show how outside factors (like friction) have affected the results.The first that I will look at is the two velocities.Here, I have put on a graph the two points velocities against the changing mass. As you can see, the velocities both increase with the mass, however they increase less every time.Also, it shows how the velocity at B, further on (therefore at a higher height) is larger than the velocity at A (at a smaller height).Theory backs both these remarks. Firstly, I shall consider the heights influence. The formula for the velocity (squared) is:v2 = 2m2ghm1 + m2As h increases, its position makes it increase the amount in the numerator, therefore directly increasing the velocity. Therefore, as Bs height is larger than As, the velocity at B will always be higher that A. A notable exception is when m2 = 0, as then the height will have no effect as the numerator, and therefore velocity will have to equal 0.Secondly, I shall consider the influence of the dropping mass. In the formula, removing the influence of the m1 would make the m2s cancel out and make the velocity the same. However, this is not so. Since the denominator involves an addition, and the numerator does not, this mean that the velocity must increase as the mass increases.As to why the graph curves, it would be easier to consider a simpler fraction, namely:x Ix+1When x = 1, the fraction is 1/2. When x = 2, the fraction is 2/3. The difference between these is 1/6. When x = 3, the fraction is 3/4. The difference between the last two is now 1/12; half of what it was before. When x = 4, the fraction is 4/5. Now, the difference between the last two is 1/20; again, nearly half. If the fraction was plotted on a graph, this downwards trend in differences would make the line curved, as it would increase less every time.This does not change with multipliers, neither in the nominator nor denominator, as they only ch ange the scale, not the shape, neither does it change when the added constant is changed. This means that the same rule applies to the formula for velocity.As for comparing this graph to the prediction, the easies way would be an overlay of the two:This shows the prediction and real graph, both scaled to fit each other. The lines from the prediction are not exactly the same as in the prediction, as I have scaled them to fit the graph. As you can see, they follow each other nearly exactly. This, coupled with the fact that my theory agreed with the graph of the results, means that my prediction must have been correct.The second graph that I will look at is the accelerationIn this graph, the trend is not so apparent. Only one definitive piece of information can be derived from this graph: that the acceleration increases as the mass increases.Before I consider the shape of the graph, I will first explain the above point. The formula for acceleration against mass is:a = m2g I(m1 + m2)As I have described in my analysis of the velocity graph, this means that as m2 increases, a must also increase. However, the fact that this increase should be smaller every time is not so apparent. To explain this, I will look at the theoretical graph on the same scale:This graph, save for a few anomalies in the actual graph, is exactly the same. Therefore there are two options: the theoretical graph is incorrect or the graph is incorrectly drawn.My suspicion is that it is the latter. I believe that the graph will turn, however not yet, i.e. that the scale is too small. If I do the graph again, with the mass going not up to 0.10 but to 1.00, the graph looks like this:The graph now does indeed curve, as I had predicted. I believe therefore that had I continued the experiment up to a dropping mass of 1 kg instead of 0.1 kg, my actual graph would also curve. This, however, only speculation, and there is no way to tell without actually doing this. I can therefore only conclude that the ac celeration increases as the mass increases. This does, conform with my prediction, however it does not prove that the graph would be hyperbolic with the asymptote at 9.81, as the graph does not go that far.E EvaluatingStandard DeviationMassVelocity AVelocity BTimeAccelerationkgm/sm/ssm/s/s0.000.000.000.000.000.010.020.050.090.030.020.020.040.020.030.030.010.040.010.040.040.010.040.010.070.050.010.060.010.140.060.020.030.010.080.070.000.090.010.230.080.010.020.010.050.090.010.020.010.050.100.050.060.010.14In this experiment, a very fair result could be achieved due to the three repeats. In fact, as this table shows, the standard deviation was never higher than 0.23, and only three times exceeding 0.10. Obviously, this could be further improved by adding more repeats.Another way to improve the results would be to better standardise the place form which the trolley was released, as on the day this was only roughly estimated, leading to anomalies. Also, although this would be only theo retical, it would have been better to decrease the friction in the wheels, runway, and pulley and even air resistance. Factors such as these lead to energy losses reaching 54%.Energy Statistics at AMassEnergykgInput (J)Output (J)Loss (%)0.000.000.00N/A0.010.040.0254%0.020.090.0636%0.030.130.0930%0.040.180.1326%0.050.220.1626%0.060.260.1928%0.070.310.2424%0.080.350.2723%0.090.400.3023%0.100.440.3423%Energy Statistics at BMassEnergykgInput (J)Output (J)Loss (%)0.000.000.00N/A0.010.090.0452%0.020.180.1232%0.030.260.2025%0.040.350.2724%0.050.440.3325%0.060.530.4123%0.070.620.4823%0.080.710.5719%0.090.790.6419%0.100.880.7120%The input in these energy losses has been calculated as the theoretical input of the appropriate mass over the appropriate distance, namely:Input = mghThe output has been calculated as:Output = v2(m1+m2)2The loss percentage has been calculated as:Loss % = Input-OutputInputObviously, at a mass of 0, input and output are 0, and therefore the loss is not calculable, as it would include division by 0.These tables show that friction and air resistance created a very large margin of error for the experiment, especially at lower masses. The real and theoretical lines are compared on the next two graphs, of the velocity at A and at B, respectively. The frication and air resistance factor would explain the difference in scale, but similarity of the lines, which would other wise have to be explained with very coincidental anomalies.It is difficult to identify anomalies on a curved graph, however, as the graph shows, the real lines quite closely follows the theoretical lines, apart from the aforementioned difference in scale. On the first graph, there is one slight bump, which could be described as anomalous, at 0.06 kg, and a slightly smaller curve than predicted at 0.01 kg, however these are the worst examples of anomalies on the graph, and are minute. On the second graph, again there is a slightly smaller curve than predicted at 0.01 kg, there is again a small bump, this time at 0.07 kg, and the point is a bit lower than it should at 0.10 kg, however again the anomalies are minute.Much worse anomalies come on the graph of acceleration. Problems due to friction and air resistance are obviously present, as the real graph is below the theoretical graph; however the real line is also, for lack of a better word, wobbly. The unsteadiness of the line makes it difficult to identify which points are actually anomalous, however by drawing a straight line of best fit (also shown), I approximate these to be at 0.01, 0.08, 0.09 kg.The increased size of the anomalies may be due to the fact that the acceleration is calculated by using three measurements, velocity at A, velocity at B and the time, all of which can have slight mistakes which add up.If factors such as friction and air resistance could not be eliminated, it might have been beneficial to measure them instead, and adjust the final results accordingly. Therefore, as further work, it w ould have been helpful to find out the co-efficient of friction of the runway, i.e. find the force needed to move the trolley (measured using a Newton meter, by pulling the trolley along the runway) and divide this by the force exerted upon the trolley by the runway (this being its weight, 0.5 kg, multiplied by the gravitational constant, 9.81, making it 4.905 N). Air resistance could also be mesaured, by Stokes law which says that air resistance force is proportional to density of the air times the cross sectional area of the object times the square of the velocity of the object.Investigation on converting Gravitational Potential energy into horizontal and vertical Kinetic Energy
