Question

a bat in search of prey hears a echo after 0 15 seconds how far
is the prey from bat if the echo got reflected from it speed of
sound in air = 30 ms

Neha Sarin · Accepted Answer

Velocity of sound, v = 30 m/s

Time taken by the sound to return from the obstacle, t = 0 15 s

Let, x be the distance between the bat and the obstacle Sound
travelled twice between bat and obstacle, firstly from bat to
obstacle and then reflected sound from obstacle to bat Thus,

2x=30 x 15= 4 5

=> x= 4 5/2 = 2 25 m

a bat in search of prey hears a echo after 0.15 seconds.how far is the prey from bat if the echo got reflected from it. speed of sound in air = 30 ms.
