------------------------------------------------- Speed Speed is defined as a measure of the distance an object travels in a given length of time. The average speed of an object can be determined from the equation below: Thus‚ if a car travels 100 meters in 5 seconds its average speed can be calculated as; Average speed = 100/5 = 20 meters per second Average speed is used to give the speed of an object over a given interval of time‚ if however the speed of an object is required for a particular moment then the instantaneous speed is used

Measuring the Speed of Sound and Air using a Pulse-Echo Technique Purpose To determine the speed of sound in air using the pulse-echo experiment procedure‚ and comparing it to the predicted speed of sound in air using the measured air temperature of the classroom. Hypothesis I believe that the speed of sound it the air will be close to that of the predicted value. According to our predicted value‚ we should expect the speed of sound in the air to be at a speed of approximately 346 m/s. Materials

I agree that the law should continue making and putting up speed limit signs. If they never put up speed limit signs our country would be crashed. There are very good reasons for them and most people disagree with these laws. Some people would be seriously injured if they did not exist. For example say you live on a really curvy road and you had to work late one night. The speed limit on you’re road was thirty-five miles per hour but‚ you were in a hurry to get home and your lights

Given the different speeds at which people may develop both physically and intellectually‚ any form of explicit age limit may be arbitrary and irrational. Children do not deserve to be exposed to criminal punishment in the same way as adults. Children have not had experience of life‚ nor do they have the same mental and intellectual capacities as adults. Persons aged 15 to 19 years are more likely to be processed by police for the commission of a crime than are members of any other population group

Cache Level 2 SHC 21 1.1 Communication is an important part to everyday living‚ there are many reasons why people communicate‚ these are not only done verbally but also non-verbally. Communication can be achieved by listening‚ questioning‚ understanding and responding. The use of facial expressions‚ and body language are a key part of communication with others. Communication should always be used to form and maintain good relationships not only with the children‚ and parents but also with

India in 21st centuries Our country has made tremendous progress after independence and we have very optimistic picture of it. If we compare the progress of these four decades with the country that India was at the close of the 19th century‚ we would wonder at the difference.The present country has achieved great success in economics‚ trade‚ industry‚ education and science. And now we can presume that India will surely occupy an important position in the world in 21st century. The day is not far

Sadie Broadway Speed of Sound In Air We are studying the speed of sound in air currently in our physics class. The speed of sound is the distance traveled by a sound wave through an elastic medium during a period of time. The speed of sound is extremely interesting‚ as it’s actually the speed of transmission of a small disturbance through a medium. The speed of sound occurs constantly‚ whenever a sound is heard. It’s everywhere‚ and in air we are discovering certain factors like altitude and air
