The Speed of "Sound": is actually the speed of transmission of a small disturbance through a medium. The speed of sound (a) is equal to the square root of the ratio of specific heats (g) times the gas constant (R) times the absolute temperature (T). a = sqrt [g * R * T] Sonic Boom Sound generated by airflow has been around and reasearched for a long time. The increased use of fluid machines and engines has led to an increasing level of noise generation, and hence to an increasing interest

Physics Investigation of Speed In this investigation I am finding out how the height of a ramp affects the speed of a toy car. To do this, I first need to know about speed and gravity. I know the equation for speed is: Speed = Distance Time From that equation I can now work out what the speed of the toy car will be, when I know the distance the ramp is and the time it took the car to come down the ramp. Now, gravity is a bit more complicated:

Speed Kills The high speed limits are often causes of accidents that cause serious injuries and even death. The speed limit should be lowered so we can control accidents caused by high speed driving, pollution, and the high cost of operation and insurance. First of all it is obvious that a motorist driving over the speed limit has more chances of getting into an accident that a motorist who is traveling at the average speed. One who drives fast does not have proper and that well of a control on the

This lab experiment was conducted in order to test the speed of sound, which is the distance traveled per unit time by a sound wave. This experiment was carried out with a certain setup, which involved materials such as a computer, a Logger Pro, a vernier microphone, two tubes, a temperature probe, a meter stick, and a dog trainer clicker. These materials were set up in a specific fashion, the Logger Pro was connected to the computer, which allowed for a temperature reading. The microphone was then

encoding the speed of a moving image has proven evasive. A variety of models have been proposed, including labelled line, ratio and Bayesian models (e.g. Priebe & Lisberger, 2004; Smith & Edgar, 1994; Thompson, Brooks, & Hammett, 2006; Hammett, Champion, Thompson, & Morland, 2007; Stocker & Simoncelli, 2006; Langley & Anderson, 2007) but there is still no clear, agreed picture of exactly where in the pathway speed-tuning arises, nor how it is achieved. The location of an unambiguous speed signal is

Finding the Speed Of Sound Analysis [IMAGE]According to the graph, an increase in the distance causes an increase in the time. This shows that they are directly proportional to each other. There is a very strong trend in the graph, which shows a strong positive correlation. I can tell this because I have drawn a line of best fit. There don't appear to be any major anomalies since all the points are either directly on the line or close to the line of best fit. This shows that the results

High Speed Pursuit: To Chase or Not to Chase? Since the origin of crime, criminals have attempted to evade justice. This is evident when criminals tamper with evidence, take hostages, and attempt to flee the scene. With the introduction of the automobile, fleeing the crime scene has become dramatically simpler. As technology increases, these automobiles are safer, handle better, and go faster than ever before. The police therefore are forced into pursuit with their own automobiles, endangering

The Speed of Light Through Perspex Planning Light travels at different speeds through different mediums. The speed of light in air is 300,000,000m/s. When light enters an optically denser medium, it bends towards the normal (refracts). You can work out the refractive index of by dividing the sine of the incidence angle by the sine of the angle of refraction and then working out the ratio of the two. Sine i Sine r From this refractive index you can work out the speed of light through

will investigate the properties of mechanical waves such as a longitudinal wave, focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory.

recent years. That includes trying to increase the speed of the cars at whatever means possible. The IRL was formed a few years ago under the direction of Tony George. He is trying to make the sport less expensive and safer by using different motors/chassis and slowing down speeds. Racing has always been about going faster than the next driver. It was about trying to beat course records and lap speeds. But if Tony George has his way, all course speeds will be reduced due to switching from turbo Indy

Speed Limits Jim was leaving work late, and he knew that his wife was at home waiting on him. She had prepared a nice meal for their anniversary and was sitting on the couch all alone. As Jim pulled out of the plant and onto newly paved two-lane highway, he noticed a large white sign with the words “speed limit” and the number “50.” It was a thirty minute drive home, and he could easily make up the time he lost at work if he could just drive as fast as he wanted. For the next half hour, however

out the Speed of Light Through Perspex Aim To find out the speed of light through Perspex by passing a narrow ray of light through a D-Block of Perspex, by using the same concepts and ideas as Snell's Law. Background Light is an electromagnetic wave. The speed of light depends on the medium through which it propagates: it goes fastest in a vacuum, almost as fast in air but considerably slower in glass. Because of the special role it plays in many parts of physics, the speed of light

Speed Skating has been around for a while now. This specific sport has many different techniquies, and skills. There is a lot more to skating then putting on shoes that have wheels and going on a wood floor skating around in circles. In 1863 James Plempton had the idea to actually invent part of the skate. After James had spent time inventing it, James had thought it would be necessary to add something more to the skate. James added what he liked to call the “Fire Rocket”, which able’s the skate
