Question

An ultrasonic wave is sent from a ship towards the bottom of the sea. It is found that the time interval between the sending and receiving of wave is 1.6 s. What is the depth of the sea,

Answer 1

Answer:

Given: v = 1400 m/s, t = 1.6 s

Let, Distance = Speed x time

2d = v x t

2d=1400m x 1.6

d=1400 x 16/2x10

we get d= 920m

hope it helps
