A ship sends out a sound signal straight down and receives its echo after one second. What is the depth of the sea at this spot? (Speed of sound in water ).

Pendulum A makes oscillations in and pendulum B makes oscillations in . Which has higher frequency? Express the frequency of each pendulum in hertz.

The frequency of a vibration is the inverse of its time period. What is the time period of a pendulum which is vibrating with a frequency of ?

The speed of sound in water is . How far away from an under-sea rock should a deep sea diver be, so that he can hear his own echo ? The diver hears echo in .

The deepest part of oceans in the world is the Marians Trench in the pacific ocean which is deep. If you were on a ship above this trench and send a sound signal straight down to the water, how long will it take for the echo to reach you? (speed of sound in water is )

A trumpeter and a clarinetist are standing well apart and playing a tune in unison(the same note together). A microphone is placed in a hall at the same distance from both of them as shown in the figure. If the trumpeter is playing louder than the clarinetist, the correct statement is:
