Question

A ship receives the sound produced by its fathometer after 3.5 seconds. Calculate the depth of the sea( speed of sound in water =1400 m/s )​

Answer 1

Given:  

Time after which the ship receives the sound= 3.5 seconds

To find:

The depth of the sea.

Solution

The speed of sound in water is 1500 m/s

Using the following relation:

Distance= speed* time

Putting the values in the equation we get:

= 1500* 3.5

On calculating the values we get the following answer:

= 5250 m

Therefore the depth of the sea is 5250 m.
