Fossil Energy - 1158 Words

Dear Michael Ruppert, After I watched your documentary interview with Chris Smith in Collapse, I know how serious the environmental problem we facing is. A hundred years ago, oil improved our society tremendously through industry. It can be regarded as the most important discovery in the 20th century. In the mean time, the use of petroleum has caused a lot of trouble. Most wars after World War II happened in the Middle East because of oil, and for this reason alone,-- I think oil is a thing that causes and has caused the most serious trouble among humans in history. Now, the whole world’s population relies on oil deeply. Since the industrial revolution of the nineteenth century, it is hard to imagine how our lives would be possible†¦show more content†¦All of these three kinds of new energy may cause more trouble than the benefits they may create. For the government, they have to develop new energy. During this year’s campaign, President Obama wants to develop new energy to create j obs. I think that is correct and the only way for America to go. To hit this target, Americans need to develop high level education to create more scientists and improve new energy technology. It will take a long time from education, find available resource, improve technology until put it into the whole market. Americans may not get benefit from it for now, but I cannot imagine how large profit they can get if they succeed in next 20 years. If American can find out a kind of new energy to substitute fossil energy totally, it will become a new supporter of economy growth. Americans can control this kind resource and set up a strong company to bring it into market, which can create millions of jobs. Usually, the owner of the resource is the same meaning of the owner of the whole world. If Americans get this new energy first, America can still roll the world for new hundred years. As I know, oil can still support Americans until 2030s. We have enough time to find the new light of the world. We still have hope. Our world may not as terrible as you said.

Lord of the Flies by William Golding - 2911 Words

The book that I am going to write about is â€Å"Lord of the Flies† by William Golding. â€Å"Lord of the Flies† is based during World War II on a deserted island. The plane, full of boys from a school, originated from Britain. The importance of the setting of the story is that the boys have been taken away from a normal society and are isolated on an island where they need to figure out their own form of society and decide on what should be considered normal to them. When we are in a society where someone has already come up with the rules and penalties; it is easy make decisions between right and wrong. When these boys are left to their own devices, they are mixed on the right way to run their community. When the boys all first realize†¦show more content†¦He eventually gains control of the majority of the group of boys and uses their fear of the beast in the woods as a way of controlling them. Ralph’s social characteristics are to lead the boys with their interests and safety in mind; he believes that order leads to control. Ralph wants to run the tribe the same way as life was at the boy’s school. Jack on the other hand is the complete opposite; he believes that the only way that he can run the tribe is to have them afraid of him. Jack and Ralph have been at odds through out the story but it really comes to a head when they argue over voting Ralph out of power. Ralph tries to restore order but Jack runs off and requests that his â€Å"hunters† join him. Throughout the day, most of the tribe goes off to join Jack. Jack seems to make the most sense, he was the one that was able to catch the food and Ralph didn’t. The unruly order of the group gets out of control during a feast when the boys are overcome with violent tendencies. Simon is coming back from the mountain after he had passed out and wants to tell the rest of the boys what he has seen. The tribe is in a crazy state of mind and they se e a figure come out of the woods and pounce on him thinking that it was the beast on the mountains.

Treated Eva Smith Essay Example For Students

Treated Eva Smith Essay In 1912, women were not treated as equal to men, although they were the ones who were doing most of the hard labour. They didnt get as much pay or respect and this was the case with Eva Smith. The working class and upper class treated each other very differently. The first thing we discover about Eva Smith in J. B. Priestleys play An Inspector Calls is that she is dead, Two hours ago a young woman died in the infirmary shed been taken there this afternoon because shed swallowed a lot of strong disinfectant, (p11). Eva Smith was a good-looking working-class woman who was very unsuccessful in many cases in her life, which lead to her death. In this essay I will be discussing that not only was Eva Smith disadvantaged by her status in society but also by the fact that she was a women. At first I will discuss how Eva Smith was treated at Birling and Company where she worked. The owner, Mr Birling was an arrogant and self-proud person who treated his women workers like machines, its my duty to keep labour costs down, (p14) and insisted that his workers worked for long hours but in return he decided to pay them very poorly. Evas status meant that she was forced to work there in the beginning as she was in desperate required money in order to survive. She had been working there for over a year and following the return of her holiday Eva Smith and some other girls requested a pay rise. The main reason for this was because the factory girls couldnt even pay their rents with the amount that Mr Birling had been paying them. He did not take them seriously because they were women and so the factory girls decided to go on strike. When Mr Birling said, he couldnt consider the pay rise, (p15) it explained to us that he took women for granted and that he didnt realise how vital they were to the running of his company. Large families to support and no money coming in resulted in the strike being abandoned very quickly and soon Mr Birling told the few main strike causers to to clear out, (p15) and so Eva Smith was sacked from her job at Birling and Company. Social status was more significant to Mr Birling than the correct moral decision and we observe this when he says, make us look a bit ashamed of ourselves in public, (p60). He also used that belief in this case and he was prepared to sack one of his best workers just so a strike similar to this one would never occur again. Eva Smiths status meant that she was very poor and was left with no job and no money to support her self, but lady luck shone on her 2 months later and she found another better-paid job at Milwards, a local fashion store. Sheila Birling was a regular customer at Milwards and an incident occurred one day when she arrived into the fashion shop looking for a dress. However when she tried it on, she caught Eva smiling at the assistant and so Sheila began accusing her of being, impertinent, (p24) and making a mockery of how she looked in the dress. Sheila complained to the manager and demanded that if Eva wasnt sacked from her job, then she would get Mrs Birling to close their account with them. Sheila used her high status to put down Eva, as she was part of the working class. By doing this the character of Sheila shows that she believed that it was acceptable to do this and in society, the high status people really ruled over the lower class and they believed that they could use their high status to their own advantage. Eva Smith was sacked in her job at Milwards because a higher class woman was jealous of Evas good looks and so intentionally got her sacked from her job. After another unfavourable incident, Eva Smith was now poor and had nowhere to live. .u82c8d022ea7cc7cb2cc3a2697fc6483d , .u82c8d022ea7cc7cb2cc3a2697fc6483d .postImageUrl , .u82c8d022ea7cc7cb2cc3a2697fc6483d .centered-text-area { min-height: 80px; position: relative; } .u82c8d022ea7cc7cb2cc3a2697fc6483d , .u82c8d022ea7cc7cb2cc3a2697fc6483d:hover , .u82c8d022ea7cc7cb2cc3a2697fc6483d:visited , .u82c8d022ea7cc7cb2cc3a2697fc6483d:active { border:0!important; } .u82c8d022ea7cc7cb2cc3a2697fc6483d .clearfix:after { content: ""; display: table; clear: both; } .u82c8d022ea7cc7cb2cc3a2697fc6483d { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u82c8d022ea7cc7cb2cc3a2697fc6483d:active , .u82c8d022ea7cc7cb2cc3a2697fc6483d:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u82c8d022ea7cc7cb2cc3a2697fc6483d .centered-text-area { width: 100%; position: relative ; } .u82c8d022ea7cc7cb2cc3a2697fc6483d .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u82c8d022ea7cc7cb2cc3a2697fc6483d .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u82c8d022ea7cc7cb2cc3a2697fc6483d .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u82c8d022ea7cc7cb2cc3a2697fc6483d:hover .ctaButton { background-color: #34495E!important; } .u82c8d022ea7cc7cb2cc3a2697fc6483d .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u82c8d022ea7cc7cb2cc3a2697fc6483d .u82c8d022ea7cc7cb2cc3a2697fc6483d-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u82c8d022ea7cc7cb2cc3a2697fc6483d:after { content: ""; display: block; clear: both; } READ: Wade Robsons Approach To Dance Drama EssayShe had become in a very bad condition and her usual hangout had become the Palace Bar.

The effect of speed on braking distance Essay Example

The effect of speed on braking distance Essay Speed is the travelled distance for every moment/unit of a set time. Speed, distance and time are all related with each other, shown in the following equation, which can be rearranged to find the formula of each measurement:Speed (m/s) = Distance (m) à ¯Ã‚ ¿Ã‚ ½ Time(s)The braking distance of an object is the distance it takes to slow the object down, until it is has stopped (stationary). The object will only become stationary when the driving force is being counter-forced, for example friction and air resistance.The kinetic energy of an object is the energy it gains due to its motion. The equation for kinetic energy is:What factors can affect the braking distance of an object?Well there are 3 main factors that affect the braking distance of an object:The height from which the object is releasedThis can affect the braking distance as the higher the object is when it is released, the greater its original GPE. As the object continues downwards, its GPE decreases, and its kinetic energ y increases by the same amount of gravitation potential energy lost. Yet still, the increase in kinetic energy is never exactly equal to the amount of GPE lost, as friction and air resistance (the forces acting on the object) transfer some of this energy into heat and sound.The surface the object is travelling onThis can affect the braking as different surfaces have a varying amount of resistance force (friction.) E.g., ice is more slippery than a rough surface because it is very smooth, and therefore exerts less friction on the object travelling on it. The friction force gradually converts the kinetic energy of the moving object into different forms of energy such as sound and heat, until the objects kinetic energy is reduced to zero hence why it always stops eventually. The longer it takes for the object to have its kinetic energy reduced to zero, the longer the braking distance.The mass of the objectThis can affect an objects breaking distance because if the mass of an object is doubled, its kinetic energy will be increased, and as a result more work will need to be done by the resisting surface to convert the objects kinetic energy into other forms of energy in order to stop it.In this experiment, I will be investigating the effect of a balls speed on its breaking distance. I will be dropping the ball from certain distances along a ramp, which is positioned at a certain height along the clamp-stand. As well as that I will also be using a carpet as I will need to slow the ball down as it travels down the ramp.MethodThere are numerous methods to measure the speed of the ball as it travels from the ramp and onto the carpet. These are the two methods that I have used during the Preliminary in order to test out which is better, and why. The following table lists both its advantages and disadvantages, of the methods, and also have brief description about each one.The table below lists the advantages and disadvantages of possible methods, and describes how they are to be carried out.NameDescriptionAdvantagesDisadvantagesStopwatchMeasure the time taken for the ball to leave the ramp when travelling on the carpet. Use the dropping distance (measured on the ramp) and the time taken to calculate the speed using the speed/time/distance formula.This is a very quick method, which is easy to execute.The stopwatch isnt very accurate; as it is very hard to know when exactly where the ball has moved along the ramp, and thus can cause confusion as one person may begin the timing of the stopwatch at a different point than when another person would tell them to, hence having an effect on the results.Light-gateConnect a light-gate device to a computer, and place it where ever you want to position it in order to calculate the balls speed, works by using a laser beam as a light sensor detecting how fast the ball is going.This method is very precise and accurate as the results itself can be displayed on the computer, as a graph or a table. So precise even t hat it can go up to six decimal places. As it being on a computer, it is easier to notice any trends or patterns in the graph/table. Also easier to transfer data across (USB)As the Light-gate is very accurate it can be a pain when setting up as the light-gate would need to be in the right place as it would cause a great effect on the results resulting in the unreliability of the results.As a result of this analysis of the methods, I decided to use the more proven and more accurate and reliable method, the Light-Gate. This is because it will be easier to record, less hassle, more time to work on the experiment as it will be very quick and easy to do, and will be easier create graphs and tables, and make conclusions from the data as it will be easier to spot any trends.The Equipment Needed.* Light-gate device* Computer/Laptop (preferably a Laptop)* Ramp* Clamp x2* Clamp Stand x2* Metre Stick(s) (depends on how far the stopping distance is)* Carpet (depends on results of Preliminary)* Ball (also depends on results of Preliminary)Here is a diagram of how it should look:Step-by-step Method1. Connect the clamp to the clamp-stand.2. Mark out regular-distance intervals along the ramp, using the metre-stick as a guide.3. Connect the ramp to the clamp, at a certain height along the stand.4. Lay the chosen carpet on the table, smoothing out any bumps.5. Position the ramp on the carpet, so that the two overlap each other at the edges.6. Connect the light-gate to the laptop.7. Place the connected light-gate in front of where the ramp overlaps the carpet.8. Place the metre-sticks horizontally along the carpet, placing the 0cm mark at the point where the ramp light gate is.9. Position the chosen ball(s) at a certain distance along the ramp (at the appropriate distance-interval)10. Release the ball, letting it travel down the ramp and onto the carpet.11. Ensure the light-gate is recording the speed of the ball.12. Measure the stopping distance of the ball on the carpet using the metre-stick. (Use a second metre-stick if the stopping distance exceeded 100cm.) (place the metre stick along the carpet aligned to the light gate)13. Repeat Steps 11 to 13 five times, re-setting the light-gate before each further trial.14. Repeat steps 10 to 14 for each distance-interval along the ramp. (All distance-intervals need to have a trial and five further repeats before continuing on to Step 16.Safety Procedures* The Apparatus shouldnt be ANY WHERE near the Computer or Laptop, as the rolling ball might causes damage to it* Clear out the space that you are using from anything, from bags to books.* No water anywhere, in fear of damage to equipment (laptops, Light gate etc.)PreliminaryBefore even doing the real experiment, we needed to make sure what equipment we were going to use in the real experiment, and so we decided to test out the equipment and to familiarize myself with the equipment to then use in the investigation. E.g. Using the Laptop correctly, prevent mistak es to happen in the real investigation. As well as that I need to ensure that the equipment that Ill be using in the investigation will be the most accurate and most reliable ones.Instead of just the equipment, I will be also testing out the:* Type of ball (golf, marble, small silver, etc.)* Type of Carpet* Ramp heightsThis I will be testing on as, I will need to know which will produce a good batch of reliable results, from which a Speed against stopping distance graph could be drawn from.The reason why Ill be testing the different ramp heights is that in order to get the best results, I will need to know what height the ramp should be as, if too high then the ball will travel too quickly/far, and vice versa. This is because the greater the height of the ramp, the greater the GPE and therefore its Kinetic Energy.The reason why Ill be testing different types of carpet, as Ill need to find out which carpet will be the best one to use, as Ill need a carpet that allows the ball to trav el a good distance on the carpet before stopping. But a bad carpet will allow the ball to go too fast/slow.Preliminary ResultsChoosing which ball to use:Small metal ball Rolled of the CarpetMedium metal ball Stopped in the carpet went straightGolf ball Curved a little on the carpetSquash ball Curved a lotFrom these results, we decided to use the medium metal ball as it was the only ball that went straight.Choosing which method to use:Firstly, we carried out a test using the stopwatch method as a way to measure the speed of the ball; we also changed the height of the ramp to increase/decrease the speed of the ball. After numerous trials, we relised that moving the ramp up and down was harder, more time-consuming and was less accurate. Using the stopwatch to workout the speed was also a very long process as we had to work out the time takenBased on the results from the Preliminary, we chose to use:* The golf ball and the marble (to compare with each other in graphs)* The light gate m ethod* Height of 15cm of the ramp* The orange carpet* Drop the ball from different points on the ramp from 10cm-90cm (this was good range as we needed a good range of results in the graph)Results Table60mReadingSpeedDistancem/smm10.8250844520.8333343530.8250845040.8389345450.8278145050mReadingSpeedDistancem/smm10.7163334320.7022527730.7102332040.7122532050.7225434840mReadingSpeedDistancem/smm10.7246432520.7418428030.7462733140.7374629350.7530131990mReadingSpeedDistancem/smm11.1210873021.106271931.1261376041.1160774951.1261372380mReadingSpeedDistancem/smm11.0548564621.0416764431.0416767641.0460365851.0416765970mReadingSpeedDistancem/smm10.9469756420.9505757030.943456940.9469758150.95057581Height Dropped (cm)Average Speed (m/s)Average Distance (mm)900.2341800.46134700.61219600.74310500.71322400.83447300.95573201.05657101.1273630mReadingSpeedDistancem/smm10.5952421220.6234421430.606820640.5952422450.6265724020mReadingSpeedDistancem/smm10.4553713720.456213330.4496413740.4664213150.46041 13410mReadingSpeedDistancem/smm10.248023920.225434030.238324040.229574350.2175843MARBLE RESULTSDiameter =1.6cmWeight = 4.2g (1d.p)Height Dropped (cm)Average Speed (m/s)Average Distance (mm)901.221080801.11926701.04791600.94659500.83538400.71416300.61312200.48200100.3093GOLF BALL RESULTSDiameter = 4.2cmWeight = 45.7g (1d.p)90 cmReadingSpeedDistancem/smm11.20413103021.22893109031.22893111041.24055112051.18243105030 cmReadingSpeedDistancem/smm10.5933529720.6093331530.6156231440.6031731550.6082031920 cmReadingSpeedDistancem/smm10.4821820520.4879220630.4605318740.4717819850.4800720410 cmReadingSpeedDistancem/smm10.307529420.297489330.287079240.296689450.294029440 cmReadingSpeedDistancem/smm10.7133241620.7172141230.71141040.6951841150.7219542950 cmReadingSpeedDistancem/smm10.828653420.8317553030.8567256340.823453050.8317553160 cmReadingSpeedDistancem/smm10.924362720.9483462830.9442467640.9415467850.9483468470 cmReadingSpeedDistancem/smm11.0253978521.0400280531.0466578741.02776551.05676811 80 cmReadingSpeedDistancem/smm11.1295295321.1141892631.0901288641.1160793451.1218932AnalysisIn this experiment, I am investigating the effect of a balls speed on its breaking distance. But in we need to be able to understand what is going on as the ball is released from the ramp and when it stops. I will try to explain this scientifically.EvaluationProblems I encountered while carrying out the experiment:How I would improve the experiment if I did it again:As the light gate needed to be at the correct place in order to get a good set of results, it wasnt always at the same place thus affecting the results.Leave it at the same place, or leave a mark so we know where we put it.When a heavy ball would roll on the plastic ramp (Golf ball), the ramp would bend, thus decreasing the speed of the ball greatlyUse a rigid material e.g. Iron, as it would not bend.The ball not travelling straight meaning the distance is decreased. (e.g. it would go diagonal)Although I managed to obtain a good s et of results from carrying out the experiment, there were several difficulties in trying to collect valid and reliable data. The following table describes the problems I encountered while carrying out the experiment, and suggestions on how I would improve the experiment if I had to repeat it.Confidence on the ConclusionOn the whole, I am quite confident with my conclusion. I attained a set of results which strongly suggested that speed of the ball had the effect on the balls breaking distance. Although, as most of the graphs show, many of the range bars are a bit large, meaning that the results are not very reliable as there is a large scatter of data, perhaps this was because of the ramp bent as the ball rolled on or that the light gate wasnt positioned correctly at that time, justifying the reason why its results was so scattered.Throughout the experiment, I had obtained many outliers in my results, as shown by the 2 Tables. These may have occurred because of any of the following reasons:* On some repeats, the position of the light gate wasnt in the same place as other repeats or therefore makingDespite these outliers, the majority of the averages were close to or on the curve of best fit, so after eliminating outliers, the results were reliable on the whole.
