Answer #1

We can easily measure the depth if we know the velocity.It is based on the principle of reflection of an echo of waves transmitted by a wave generator and the time is noted for the wave to return, Knowing the velocity of the wave and the time to return back, it is possible to calculate the distance traveled by the wave using the simple mathematical formula.

Since the wave has to travel up and down the actual depth is nearly half the distance so if d is the depth,

.

its a basic method to measure the depth. But we did not know the velocity also. So we can use sound waves to find the depth. the velocity or speed of sound wave is 1500 m/s . So we can use this value and find the depth easily.

Consider an infinitesimal segment of the string located at distance x = 1.00 m from the tip of the lever, at t = 20.0 ms. At t= 20.0 ms, the perturbation has already reached that segment but the wave has not reached the pulley yet (so there is no reflected wave). Confirm this. How far from its equilibrium position is this segment at t= 20.0 ms? Is it below or above its equilibrium position? What is the velocity of this...
