Question

in a submarine filled with a sonar,the time interval between the generation of an ultrasonic wave and the receipt of its echo is 200sec. wats the distance of the enemy submarine? the speed of sound in water is 1.450km/s.​

Answer 1

Answer:

Let distance covered by submarine be X

and total distance be 2X

We know that, Velocity = Distance / time

So,

A/q,

1.450 × 200 = 2x

290 = 2x

X = 290/2

X = 145
