Explanation The concept we must use to solve this problem is average acceleration and force. The average acceleration is the change in velocity with respect to the elapsed time. So, the expression for the average acceleration is given as below: a avg = v − u t …… (1) Here, v is the final velocity, u is the initial velocity and t is the time. The force on an object is calculated by using the Newton’s second law of motion as given below: F avg = m a avg …… (2) Given: Mass of the baseball m = 0.140 kg Distance s = 11.0 cm Initial speed u = 0 m/s Initial speed v i = 35.0 m/s Formula used: a avg = v − u t F avg = m a avg Calculation: Initially, we must find a time by using the expression of average speed as given below: v avg = 35 2 = 17.5 m/s Thus, the time is – t = d v avg = 0...

A spectra is a graph that has amplitude on the Y-axis and frequency on the X-axis. A harmonic spectra simply draws a vertical line at each frequency that a harmonic would be produced. The height of the line indicates the amplitude at which that harmonic would be produced. If the Fo of a sound is 125 Hz, please sketch a spectra (amplitude on the Y axis, frequency on the X axis) of the harmonic series up to the 4th harmonic. Include actual values on Y and X axis.

Sketch a sign wave depicting 3 seconds of wave activity for a 5 Hz tone.
