Answer» Answer: ANSWER Let the distance between the ship and the enemy SUBMARINE beS. Speed of sound in WATER =1450m/s TIME lag between transmission and reception of Sonar waves =77s In this time lag, sound waves travel a distance which is TWICE the distance between the ship and the submarine (2S). Time taken for the sound to reach the submarine = 2 1
×77=38.5s Distance between the ship and the submarine, S=1450×38.5=55825m=55.8km please mark as brainlist answer and follow me please THANK answer |
