A sonar fitted in a submarine sends ultrasonic waves which reach it again after reflecting from another submarine in 50 seconds.what is the distance between the two submarines?
In fresh water, the speed of sound at 25 degree celsius is 1497 m/s.let the distance between the submarine is x, thenTotal distance=speed*time2x=1497 * 502x=74850x=74850/2=37425Hence the required distance is 37425 m.Thanks & RegardsRinkoo GuptaAskIITians Faculty
