A submarine emits a SONAR pulse, which returns from an obstacle underwater cliff in 1.02 s. If the speed of sound in salt water is 1531 m/s, how far away is the cliff?​

\huge\mathfrak\purple{Solution:-}

Time between transmission and detection of SONAR pulse, t= 1.02 s

Speed of sound in salt water, v= 1531 m/s

Distance of the cliff = d (say)

Then the distance travelled by the sound would be 2d

But,

2d= Speed of the sound × time = vt

2d= 1531 × 1.02 m

d= 1531 × 1.02/2

=> d= 780.81 m. Ans.

Hope it helps...:-)
