Explanation Given that the person travels 1 3 of the distance at the speed of 2 v . Consider the person travels x distance at the speed of 2 v . Write the expression for time taken by the person to travel x distance at the speed of 2 v . T 1 = 1 3 x 2 v (I) Here, T 1 is the time taken by the person to travel x distance at the speed of 2 v . Given that the person travels 2 3 of the distance at the speed of v . Consider the person again travels x distance at the speed of v . Write the expression for time taken by the person to travel x distance at the speed of v . T 2 = 2 3 x v (II) Here, T 2 is the time taken by the person to travel x distance at the speed of v . Write the expression for total time taken by the person. T = T 1 + T 2 (III) Here, T is the total time taken by the person. Use equation (I) and (II) in equation (III)

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.
