Question

A stone is dropped into a well in which the level of water is h below the top of the well. If v is velocity of sound, the time T after which the splash is heard is given by(a) $T = \frac{2h}{v}$(b) $T = \sqrt{[\frac{2h}{g}]} + \frac{h}{v}$(c) $T = \sqrt{[\frac{2h}{v}]} + \frac{h}{g}$(d) $T = \sqrt{[\frac{h}{2g}]} + \frac{2h}{v}$

Answer 1

the answer is c part
