A research team sends a sonar signal to confirm the depth of a sea. They heard an echo after 6s.Find the depth of the sea if speed of sound in water is 1500 m/s.

Text Solution

Verified by Experts

Let the depth of the sea = d m
Then Total distance
travelled by sonar signal `(s) = 2d`
`=1500 m//s`
Total time taken `(t) = 6s`
From, `s= ut`,
`2d=1500 m//s xx 6s`
`d=9000//2 m=4.5` km

The echo of the sound of an explosion from the bottom of an ocean was heard after 10 sec of its occurrence. If the velocity of sound in water be 1500 m//s , the depth of the ocean at the place is :

To hear the echo of a sound, the minimum distance between, listener and the reflector should be speed of sound in air =340 m/s)

A tuning fork of unknown frequency produces 5 beats per second with another tuning fork. The second fork can cause a closed organ pipe of length 40 cm to vibrate in its fundamental mode. The beat frequency decreases when a small amount of wax is dropped on the first fork. Find out the frequency of the first tuning fork. Given, speed of sound in air = 320 m * s^(-1) .

A diver sends an audio signal from some depth under water. This signal produces 5 beats per second with the note emitted by a 20 cm long pipe whose one end is closed. Find out the frequency and the wavelength of the audio signal inside water. Given , velocity of sound in air = 360 m * s^(-1) and that in water = 1500 m * s^(-1) .

Sea water is splattered horizontally from a jet at a speed of 10 m cdot s^(-1) . The water comes to rest after falling in a container, 20 m below the jet level. What will be the increase in the temperature of the water? Specific heat of sea water = 0.94 cal cdot g^(-1) cdot^(@)C^(-1), J = 4.2 xx 10^(7) erg cdot cal^(-1) .
