------------------------------------------------- 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

They are meant to slow us down‚ keep us safe from dangerous drivers and provides enforcement for the law. However is this nuisance really helping? I think not. The cameras are often inaccurate and ineffective. They also require regular

GEARBOX DESIGN PROJECT DESCRIPTION You are the designer and you have been asked to design a speed reducer that will take power from the shaft of an electric motor rotating at 1500 rpm and deliver it to a machine that is to operate at approximately 750 rpm. Assume that you have decided to use spur gears to transmit the power and you are proposing to use a single-reduction speed reducer. The power to be transmitted by the shaft is 20 KW and the input shaft is coupled to the motor shaft

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
