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

should be illegal to drive while using a phone because it distracts drivers from the road and makes the roads unsafe. Although some believe it should not be illegal‚ actually it should because driving and being on the phone is one of the main causes for death and accidents in the United States. While driving‚ if someone looks at their phone for more than three seconds it doubles the chance of getting into an accident. A driver on their phone may not have their eyes on the road‚ so they might not

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

A Self Driving Car is smarter than a human because it can do things faster than we can do. When we do repetitive tasks we tend to become easily distracted and the result is that people text‚ eat‚ fall asleep‚ etc. Self-driving cars are able to maintain the same level of alertness 100% of the time. Of the self-driving cars already on the road‚ there is a clear track record of safety with the majority of accidents being the result of human errors from the other drivers. Self-driving cars would

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
