A man holding a sound source at the top of a tower emitting frequency of sound as `v=1000Hz`. Suddenly it slips from his hand and falls down with `'g'` acceleration. The frequency of sound heard by the man at `t=4sec`. (Velocity of sound `=320m//s`, `g=10m//s^(2)`)

A

`860 Hz`

B

`888Hz`

C

`894.75 Hz`

D

`930 Hz`

To solve the problem, we need to determine the frequency of sound heard by the man at \( t = 4 \) seconds after the sound source has slipped from his hand and is falling under the influence of gravity. We will use the Doppler effect to find the apparent frequency. ### Step-by-Step Solution: 1. **Identify the Given Values:** - Frequency of the sound source, \( v = 1000 \, \text{Hz} \) - Velocity of sound, \( v_s = 320 \, \text{m/s} \) - Acceleration due to gravity, \( g = 10 \, \text{m/s}^2 \) ...
