In a submarine fitted with a SONAR, the time between the genretaion of an ultrasonicwave and the reciept of its echo is 200 s. What is the dsistance of the enemy sun=bmrine ? The speed of the sound in water is `1.450 km s^(-1)`

A SONAR (sound navigation and ranging) uses ultrasonic waves to detect and locate object under water. In a submarine equaipped with as SONAR, the time delay between genration of a probe wave and the recption of its echo after refection from an enemy submarine is found to be 77.0 s. What is the distance of the enemy submarine ? (speed of sound in water = 1450 ms^(-1)

A person clapped his hands near a cliff and heard the echo after 2 s. what is the distance of the cliff from the person if the speed of the sound. v is taken as 346 ms^(-1) ?

A SONAR system fixed in a submarine operates at a frequency 40.0kHz. An enemy submarine moves towards the SONAR with a speed of 360 km h^(-1) . What is the frequency of sound reflected by the submarine ? Take the speed of sound in water to be 1450 ms^(-1) .

A sonar system fixed in a submarine operates at a frequency 40.0 kHz, An enemy subarine moves towords the sonar with a speed of 360 km/h. What is the frequency of sound refielcted by the submarine? (Take the speed of sound in water to be 1450 m/s)

If the same time taken for the reflected sound to reach the sonar os 2 s, the depth of the sea is _______ m. (velocity of sound in water is 1500 ms^(-1) )
