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

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

Reasons People Speed Drivers are supposed to abide by the speed limit while driving‚ but they often exceed it for several reasons. The reasons seem to serious sometimes‚ but most cases‚ they seem to funny and ridiculous. Some people go over speed because they are late for work or private appointment. Furthermore‚ other people do over speed because of their physiological emergency. Every speeding has completely diverse reasons under specific driving circumstances. First‚ people do

Part 2 Final Project: Motor Speed Control Introduction and Objectives In this lab you will control the speed of a motor. Figure 1 shows the hardware setup‚ which is the same as for Week 1 of Lab 4. You will use the potentiometer on your evaluation board to set the desired speed of the motor‚ and you will control the speed through the PWM output of the HCS12. You will measure the speed of the motor using an input capture pin‚ and display the desired and actual speeds on the terminal.. 1. The

Clocking the Speed of Light Why is the speed of light important? -Having a accurate number for the speed of light allows for accurate measurements of the universe around us -Even small inaccuracies make large differences when measuring the space between stars‚ planets‚ and galaxies -The more precise our measurement of the speed of light the more precise our measurements are of the universe because light is the universal measurement used Light as Infinite -Most scholars agreed that light
