A sonar device on a submarine sends out a signal and receives an echo 5 s later. Calculate the speed of sound in water if the distance of the object from the submarine is 3625 m.

Asked by Vishal kumar | 1 year ago |  246

##### Solution :-

Time (t) taken to hear the echo = 5 s

Distance (d) of object from submarine = 3625 m

Total distance travelled by SONAR during reception and transmission in water = 2d

Velocity (v) of sound in water = $$\frac{2d}{t}=\frac{(2\times 3625)}{5}$$

= 1450 ms-1
