Answer 1

Answer:

To find the sunken ship an ultrasonic

pulse was sent and was detected after 0.5

seconds. Calculate the depth at which the

ship was found. The velocity of sound in

sea water is 1700 m/s.

Answer 2

Answer:

The depth at which ship was found is 425m

Explanation:

Let depth of sea is x

Distance Traveled by Sound wave = 2d

( ∵ the sending wave distance = d and detected wave distance = d , therefore total distance traveled is their sum)

Time is taken by sound ways for 2d distance, t = 0.5sec

Speed of sound wave in sea water = 1700m/s

Formula used Here:

Speed of sound wave in sea water = $\frac{total distance traveled}{total time taken}$

$1700=\frac{2d}{0.5}$

d = (1700×0.5) / 2

d = 850 / 2

d = 425 m

Therefore, the depth at which the ship was found is 425 m.
