The frequency of a tuning fork is 350 Hz . Find how many vibrations it executes while the sound produced by it travels a distance of 70 m . (velocity of sound in air `330 m s^(-1)` ) .

The frequency of a tuning fork is 600 Hz. What is the number of vibrations made by the tunning fork, when the sound produced by the tuning fork travels a distance of 110 ? (Velocity of sound in air is 330 ms^(-1) )

Find the number of vibrations made by a tuning fork of frequency 480Hz during the time the sound travels a distance 220m. Velocity of sound =330ms^(-1) .

The frequency of a tuning fork is 150 Hz and distance travelled by the sound, produced in air is 20 cm in one vibration. Calculate the speed of sound in air.

The frequency of a tuning fork is 150 Hz and distance travelled by the sound, produced in air is 20 cm in one vibration. Calculate the speed of sound in air.

A tuning fork has frequency 512 Hz. The number of vibrations of the fork in the time during which the sound from the tuning fork reaches 332 m in air are (velocity of sound in air is 332 m//s .)

Two tuning forks A and B of frequencies 200 Hz and 400 Hz are vibrated simultaneously. Then, the ratio of time taken by the sound produced by A and B to travel 660 m and 990 m, respectively in air is ______ (velocity of the sound in air = 330 m s^(-1) )
