Question

In a SONAR ultrasonic waves are sent into the seawater and the reflected waves from a sunken ship are received after 2s. If the velocity of waves in seawater is 1450m/s. Find the depth of the sunken ship.

Answer 1

Answer:

2900 m

Explanation:

1450×2

xD

hope it helps

Answer 2

Answer:

Given,

 Speed of ultrasonic wave in water, V=1450 ms−1

Time taken ,t=2 s

Let the depth of the sea be d, then total distance covered by wave = 2d

Depth of sunken ship, 2d=Vt 

∴d=Vt2

d=1450×2/2

d=1450 m
