Car speeds

Introduction
Along the David low way in colon coming up to the Pergian roundabout the speed limit is 60km/hr this is a change in speed from the highway which is 80km/hr the speed change here is because it is in a suburban area and a school zone. Speed limits are needed on our road to help prevent accidents and car collisions. The formula for speed is d/t=s (distance over time equals speed)

Aim
The aim of this prac was to use a simple technique to measure the straight line speed of cars on the David low way.

Hypothesis some cars along the David way will speed
Methods
Cars
Drivers
Stop watch
Football posts
We organized our selves into groups of 3 with one person at each football post and one to write down our times.
The football posts on the far oval where used as start and finishing points. We stood at opposite ends of the oval in a straight line with each other. We chose a car travelling down the road and when it passed the first person they swung there arm to indicate that it was time to start timing the car.
The time was them measured for 100m and calculated to have a sum of km.hr. We repeated this process for 5 cars driving each direction.
All the results where then recorded into a data table.

Results the data was collected by writing down the times and distances of each car and the formula d/t = s was used to get the answer in a result of m/s this was them multiplied by 3.6 to get a result of km/hr. Table a Car description | Distance (m) | Time (s) | Speed (m/s) | Speed (km/hr) | White 1 | 100 | 6.75 | 14.8 | 53.28 | Honda | 100 | 5.90 | 16.9 | 60.84 | Toyota | 100 | 5.45 | 18.3 | 65.88 | Suzuki | 100 | 5.87 | 17 | 61.2 | White 2 | 100 | 8.66 | 11.5 | 41.4 | Blue 1 | 100 | 8.49 | 11.8 | 42.48 | Blue 2 | 100 | 6.1 | 16.4 | 59.04 | Truck | 100 | 6.11 | 16.4 | 59.04 |…...

...ESPN X Games: Commercialized Extreme Sports for the Masses SMGT 798 Allison Renard A Paper Presented to the faculty of Lasell College in Partial Fulfillment of the requirement of the Degree Master of Science in Management. ABSTRACT For years, extreme sports had little to nothing in common with each other except for high risk, and an appeal to women and men from the ages of 12 to 34. Entertainment Sports Programming Network (ESPN), realizing this age group was a prime viewing audience, brought together several extreme sports and created yet another commercialized sporting spectacle. Since 1995, this television network has produced the Summer X Games. After these summer productions proved to be successful television and live spectator events, ESPN expanded into the winter extreme sports. The Winter X Games have been produced since 1997. This paper, which commences with the rise of extreme sports, is an historical and sociological analysis of the creation and growth of the ESPN X Games. While these commercialized adventure and extreme sporting events have had some obvious growing pains, both the Summer and Winter X Games have grown into events, which annually attract thousands of spectators and viewers while offering fame and a few dollars to their participants. INTRODUCTION One need only take a quick glance at the daily news to discover that society in general is still in a state of constant change (Leonard, 1993). In the United States, this is especially......

Malcolm X

...Hunter Dixon Mrs. Richardson Term Paper Final Draft 08 December 2013 The Angriest Man In America Without a doubt, Malcolm X is one of the most iconic figures in the history of our country. He is best remembered for the passion and power he displayed during all of his speeches, but his legacy has roots so much deeper than just that. He was the self-proclaimed “angriest man in America,” and he even openly called white people devils. Malcolm spent his whole life preparing himself for an inevitable death (Malcolm X, A Leader of Black Pride). He wanted to get his message out to the world before his time came, and it came much too early for a man like him. Malcolm X will live on throughout history because he was so passionate in his beliefs; though they changed often, he always stood up for what he believed was right, and there is nothing more respectable than that. Even if the man’s beliefs were radical at times. Malcolm’s birth name was Malcolm Little. He was born in Omaha, Nebraska on May 19, 1925 to parents Rev. Earl and Louise Little, the fourth of eight children (The Autobiography of Malcolm X). When he was about a year and a half old, his parents decided it was best to move out of Omaha after a Klu Klux Klan band warned them to leave, or else face consequences (Malcolm X). After passing through Milwaukee for a short time (Malcolm X, A Leader of Black Pride), they eventually found a place to stay, in Lansing, Michigan. Even though they had a new home, the......

...Science: A Blessing Or A Curse Everything in the universe has its uses and abuses. The same applies to science. Science has revolutionized human existence and has made it happier and more comfortable. Modern science has many wonders. Electricity is one of its greatest wonders. It is a source of energy. It can run any type of machinery. With the help of electricity, we can light our rooms, run buses and trains and machinery, lift water for irrigation and can accomplish a multitude of other tasks. Much of the progress that mankind has made in different fields right from the stone age to the modern age is due to the progress made in the filed of science. Not only material progress but also the mental outlook of man has been influenced by it. Agriculture, business, transport, communication and medicine to name a few are all highly indebted to the wonders of science. We have become scientifically much more advanced than our ancestors. This is because the world has undergone a tremendous change because of the rapid strides made by science and technology. The discovery and development of a large number of powerful energy sources – coal, petroleum, natural gas, electricity etc. – have enabled humanity to conquer the barriers of nature. All these have facilitated the growth of fast modes of transport and communication, which have metamorphosed the world into a global village. Science has given man the means of travelling to the moon. Science is a great help in the agricultural......

...Science split second late or a few inches off the mark, and few would remember. Instead, running with his back to the ball, Willie Mays extended his arm and placed his glove squarely under the 420-foot center field drive. The New York Giants win Game 1 of the 1954 World Series, and Mays, his glove, and “The Catch” earn their place in history. Few of our limb movements will ever gain such immortality, but what we accomplish every day is remarkable, nonetheless. When we catch a tipped wineglass or launch a dart toward a bullseye, hardly a second thought is given to the intricacy of neural circuits that orchestrate such precise movements. How do these circuits control skilled behaviors? Because rodent limb movements are strikingly similar to those of primates ( 1), and mice provide a means of manipulating neuronal subtypes selectively ( 2), as a postdoc with Tom Jessell I reasoned that a detailed quantification of mouse reaching, together with a genetic dissection of spinal circuits, might help disentangle core features of mammalian skilled motor control ( 3). Reaching appears simple, but deceptively so. Motor neurons fire, propelling the arm to target. Yet reaching does not arise from an isolated burst of motor output; rather, motor neuron activity is continually tweaked to shape appropriate limb kinematics ( 4– 6). One strategy for updating motor output is to use proprioceptive feedback from muscles to evaluate outcome and correct course...

Before industry standards came into play, the proprietary computing environment bred a kind of technical arrogance that, fortunately, won’t fly anymore. Once standards were established, the customer started to define what was going to be successful, and it didn’t matter what you invented or how good it was or how fast it was. Increasingly, what matters is what the customers want and whether it works with all their other stuff. That means we have to stay on top of our customers’ needs, and we have to monitor and understand the innovations in the material science world – everything from semiconductors to polymers to liquid crystal displays. You need to track anything having to do with the flow of electrons, and you need to keep asking how these marvelous developments might be useful to customers. The customer doesn’t come to you and say, “Boy, I really like lithium ion batteries. I can’t wait to get my hands on some lithium ion.” The customer says, “I want a notebook computer that lasts the whole day. I don’t want it to run out when I’m on the plane.” I was about to leave a meeting at Sony in Tokyo in January of 1993 when someone ran up to me and said, “Oh, Mr. Dell, please wait one minute.

If we doubled the magnifying power of the most powerful optical microscope in the world, we would still not be able to see an atom. 4. Chemical compounds are made up of about 100 distinct elements. Atoms are the smallest subdivision of matter that still retains chemical properties of a substance. A quark is the smallest particle that exists. Electrons form atoms that in turn determine chemical properties of a substance. 5. The number of protons makes an element distinct. 6. Brownian motion has to do with random motions of atoms and molecules. 7. A quark is the smallest particle. 8. A molecule has structure, mass, and energy. 9. Solid matter is mostly empty space. Electrical forces prevent the solids from falling through one another. 10. Electrical forces determine the chemical properties of an atom. 11. The air in this room had no energy, no weight, and no mass. 12. Assuming all the atoms exhaled by Julius Caesar in his last dying breath are still in the atmosphere, then we probably breathe one of those atoms with each single breath. 13. Nuclei of atoms that make up a newborn baby were made in ancient stars. 14. The reason a granite block is mostly empty space is because the atoms in the granite are mostly empty space themselves. 15.

X-Ray

...X-Radiation Project Abstract This project will look at the history of X-radiation in its notable historical forms and trace the use of the technology all the way to contemporary forms of X-Radiation, including computed tomography. The origins of the two technologies will be traced as well as the improvements that have been made to them over the past number of decades. The importance of the technology will be assessed in terms of its efficiency and usefulness in the context of modern medicine. The finding is that CT, CAT, and X-ray allow for great convenience, lower cost, and higher quality imaging than is possible without these technologies. Background & State of the Art The story of X-rays begins in the late Nineteenth Century when a German professor named Wilhelm Conrad Roentgen introduced the discovery that a cathode ray tube could create a fluorescent glow of crystals that were placed on a surface near the tube (NA, 2014). After giving the cathode ray tube a higher voltage and removing all air from the inside of the tube, the professor found that the tube gave nearby objects a fluorescent glow of light. The upshot for the professor from this improvised experiment was that the tube must be giving off a new kind of ray that scientists were not yet familiar with. The most significant part of Roentgen’s discovery, for modern medical purposes, at least, was that the new......

Malcolm X

...Wesley Maschke D. Allen University Writing 28 January 2016 Malcolm X Reading the essay as a whole, I found it very interesting and enlightening to a side of thinking that I have never done before. It's astounding how a man can go from being an almost illiterate convict to a very knowledgeable reader, while in prison. One thing that bothered me about the content was the story about Nat Turner. It seems as if all of the African community applauds Nat for his actions. I believe that Nat’s actions and the commandment of those actions negate any sort of pity that should be felt for the African community. Even if the white people were being outlandishly evil to the blacks, it does not give the blacks any sort of right to retaliate and kill white people out of anger. I believe the ways of Martin Luther King Jr. were the most ethical and respectable ways to go about the civil rights movement. Peace and patience are a lot more respectable than violence when it comes to achieving a goal. On the other hand, I agree with Malcolm X in the fact that what white people have done is completely inexcusable. The writing of this piece is also very interesting. The chronological arrangement of Malcolm’s life adds to the effect of how much being in prison actually changed him. The addition of other outside sources that drove Malcolm for change makes his new lifestyle appear to be very noble. A quote that describes the differences in jail and outside of jail is, “Some were said by many to be...

Malcolm X

...Kenya Davis Ms. Howard Sociology 02 March 2016 MLK Jr vs Malcolm X Martin Luther King Jr and Malcolm X had many similarities and differences when it came to their roles in the civil rights movement. A huge similarity of the two is they fought hard for their people with getting treated bad. They both wanted to see black people in the best position possible. Risking their lives everyday for the rights they felt they deserve. They were both assassinated because of their leadership role positions they played during this time. Even though they had different beliefs/religions, both their religions played a significant role in their approaches. They both had the greatest impact on the civil rights movement during the 1960s. One of the main reasons why Malcolm X and MLK Jr is different is their approach to the civil rights movement. While MLK Jr wanted to keep the peace and have a non-violent protest, Malcolm X was very opposite. Malcolm X felt that if they wanted to be violent then so should his people. Also, MLK Jr thought more of people being equal and Malcolm X was more for his people being in high power and being controlled by themselves. Also, their religion was a extremely huge difference and had an impact on the way they went about things. MLK Jr grew up in a Christian home where his parents stressed necessary things such as education and religion. Malcolm X converted to Islam after being arrested for drugs and burglary. His outlook on things were far more violent...

Generation X

...The Generation X. INTRODUCTION Generation X includes those people who are born between the early 1960s(nineteen sixtys) and the early 1980s(nineteen eightys). This generetion is likely presented by our parents. Gen X are trapped by two much larger generations – the Baby Boomers ahead and the Millennials behind – that are completely different from one another. Gen X grew up in an era of emerging technology, political and institutional changes. This generation spent less time with their parents than previous generations of children had. They found themselves home alone and taking care of themselves and their siblings, while their parents worked. They were not coddled for every emotional need and want. IN WORKPLACE They learned independence early in life and turned it into a valuable hallmark as they progressed in the working world. In Generation X, we see a highly independent, outspoken, adaptable and fearless group of employees who can move your company forward with their ability to lead for example, their competence and their willingness to take risks necessary for corporate growth. The workplace challenges for this group are less likely to be related to independent project management or leadership. In addition to the workplace issues facing the general employee population, the Gen X worker will more likely struggle at work with: career development; conflict resolution and office politics; multigenerational team projects. Now I want to mention some of work style......

...Elimination rate constant Consider a single IV bolus injection of drug X (see Figure 1.2). As time proceeds, the amount of drug in the body is eliminated. Thus the rate of elimination can be described (assuming first-order elimination) as: dX dt kX Hence X X0 exp( kt) where X amount of drug X, X0 rate constant. dose and k first-order elimination Volume of distribution The volume of distribution (Vd) has no direct physiological meaning; it is not a ‘real’ volume and is usually referred to as the apparent volume of distribution. It is defined as that volume of plasma in which the total amount of drug in the body would be required to be dissolved in order to reflect the drug concentration attained in plasma. The body is not a homogeneous unit, even though a one-compartment model can be used to describe the plasma concentration–time profile of a number of drugs. It is important to realise that the concentration of the drug (Cp) in plasma is not necessarily the same in the liver, kidneys or other tissues. Thus Cp in plasma does not equal Cp or amount of drug (X) in the kidney or Cp or amount of drug (X) in the liver or Cp or amount of drug (X) in tissues. However, changes in the drug concentration in plasma (Cp) are proportional to changes in the amount of drug (X) in the tissues. Since Cp (plasma) Cp (tissues) i.e. Cp (plasma) Cp (plasma) Vd X (tissues) Then X (tissues) where Vd is the constant of proportionality and is......
