Question

The deapth of sea is 2km the time for the reflected sound to reach the sonar is(take velocity of sound in water is 1500ms-1)

Answer 1

❗❗hello buddy here is ur answer,,,❕❕


Given: distance=2km

v= 1500ms^-1

then time= t = d/v

d= 2km= 2000m


t = 2000/1500 = 1.33 second...


hope it helps u⏩⏩⏩

Answer 2

answer is 2.67

soln:  2km=2000m

therefore:time taken to hear the reflected sound = 2x/v

=2x2000/1500

=4000/1500

=2.667
