A ship uses pulses of sound to measure the depth of the sea beneath the ship. A sound pulseis transmitted into the sea and the echo from the sea-bed is received after 54 ms. The speedof sound in seawater is 1500 m / s.Calculate the depth of the sea beneath the ship

A submarine emits a SONAR pulse which return from an under water cliff in 1.05 second. If speed of sound in salt water is 1531 m/sec. How far away is the cliff.Select an answerA803.7 mB765.5 mC1568 mD1607.4 m

A SONAR on a ship sends a signal to the ocean floor and receives the reflected signal.The speed of the signal in water is 1400 metres per second.The ocean floor is 7 kilometres below the ship. Question promptHow long will the signal take to go to the ocean floor and come back to the ship?

A device at the bottom of the sea emits a sound wave of frequency 200 Hz.(i) The speed of sound in sea-water is 1500 m / s.Calculate the wavelength of the sound in sea-water.

A sound wave travels from air into water.  In air, the sound wave travels at a speed of 340 m/s and has a wavelength of 20 m, and in water, it travels at a speed of 1500 m/s.  Calculate the wavelength of the sound wave in water.88.24 m4.53 m0.01 m25,500 m

Two sailors are trying not to get seasick as their ship plows through waves on the ocean. They notice the ship bobs up (crest), back down again (trough), and back up (next crest) every 4 seconds.If the speed of these waves relative to the ship is 3 m/s, how far apart are the wave crests (in meters)?
