A submarine that is not moving sends out a sonar sound wave travelling at 2000 `m /s` is, which reflects off a boat back to the submarine. The sonar crew detects the reflected wave 8 s after it was sent out. How far away is the boat from the submarine ?

To solve the problem, we need to determine how far away the boat is from the submarine based on the time it takes for the sonar sound wave to travel to the boat and back. ### Step-by-step Solution: 1. **Understand the Problem**: - The submarine sends out a sonar sound wave that travels at a speed of 2000 m/s. - The total time taken for the sound wave to travel to the boat and back to the submarine is 8 seconds. ...

An ultrasonic transducer used in sonar produces a frequency of 40 kHz. If the velocity of the sound wave in seawater is 5050 ft/s, what is the wavelength ? The transducer is made to emit a short burst ofsound and is then turned off. The receiver is turned on. The pulse is reflected from a lurking submarine and received 5.0 s after it was first emitted. How far away is the submarine ?

A helicopter is trying to land on a submarine deck which is moving south at 17m/s. A balloon is moving at 12m/s with wind into the west. If to the submarine crew the helicopter is descending vetically at 5m/s, what is its speed? (a) relative to the water and (b) relative to the balloon. See fig.

The velocity of ultrasonic sound in water is 1400 m s^(-1) . The depth of the ocean as detected by SONAR if the time taken to receive the reflected wave is 15 s , is "________" .

Two submarines are approaching each other in a calm sea. The first submarine travels at a speed of 36 km h^-1 and the other at 54 km h^-1 relative to the water. The first submarine sends a sound signal (sound waves in water are also called sonar) at a frequency of 2000 Hz. (a) At what frequency is this signal received by the second submarine ? (b) The signal is reflected from the second submarine. At what frequency is this signal received by the first submarine. Take the speed of the sound wave in water to be 1500 m s^-1 .

A sonar device on a submarine sends out a signal and receives an echo 5 s later. Calculate the speed of sound in water if the distance of the object from the submarine is 3625 m ,

An indian submarine is moving in the Arabian sea with constant velocity. To detect enemy it sends out sonar waves which travel with velocity 1050(m)/(s) in water. Initially the waves are getting reflected from a fixed island and the reflected waves are coming back to submarine. The frequency of reflected waves are detected by the submarine and found to be 10% greater than the sent waves. Now an enemy ship comes in front, due to which the frequency of reflected waves detected by submarine becomes 21% greater than the sent waves. Q If the wavelength received by enemy ship is lamda' and wavelength of reflected waves received by submarine is lamda'' , then ((lamda')/(lamda'')) equals
