Answer:25.873 m
Step-by-step explanation:
Original frequency

Acceleration due to gravity =9.80 m/s^2
Observed frequency

When the source is receding from stationary observer then

Distance tuning fork has fallen to reach this speed



Time required to reach the sound to the observer


t=0.071 s
During this time fork has traveled an additional distance of
