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.

Answer 2

Answer:

answer is 2625 m/s
