Question

A SONAR transmits an ultrasonic sound signal towards the bottom of a sea. The time interval between the transmitting and the receiving of sound waves is 2 seconds. If the speed of ultrasonic sound in seawater is 1560 m/s, find the depth of the sea​

Answer 1

Answer:

The answer will be 1560m or 1.56 Km.

Explanation:

We have given;

          The time interval between the transmitting and receiving of sound waves = 2 seconds

           The speed of ultrasonic sound in seawater = 1560 m/s;

Now, time for ultrasonic sound to reach the bottom of sea = 2 / 2;

                                                                                                  = 1 second;

Distance Travelled = Velocity * Time;

                                = 1560 * 1;

                                = 1560m or 1.56 Km.

That's all
