A tuning fork when sounded with tuning fork of frequency 256 produces `4 beats//sec` and when sounded with another of frequency 250 produces `2 beats//sec` . The frequency of the fork is -

A tunning fork produces 6 beast/s when sounded with a tuning fork of frequnecy 256 Hz. The same tunning fork when sounded with another tunning fork of frequency 252 Hz produces 2 beat/s. Find the frequency of the tunning fork.

A tuning fork produces 4 beats // s when sounded with a fork of frequency 512 Hz. The same tuning fork. When sounded with another fork of frequency 514 Hz produces 6 beats // second. Find the unknown frequency of the fork.

A tuning fork of frequency 256 Hz produces 4 beats per second when sounded with a stringed instrument. What is the frequency produced by the instrument?

A tuning fork sounded together with a tuning fork of frequency 256 emits two beats. On loading the tuning fork of frequency 256, the number of beats heard are 1 per second. The frequency of tuning fork is

A tuning fork sounded together with a tuning fork of frequency 256 emits two beats. On loading the tuning fork of frequency 256, the number of beats heard are 1 per second. The frequency of tuning fork is

A tuning fork of unknown frequency when sounded with another tuning fork of frequency 256 Hz produces 4 beats per second, and on loading with a little amount of wax, it again produces 4 beats per second. The unknown frequency is____________.

A tuning fork of unknown frequency x, produces 5 beats per second with a tuning fork of frequency of 250 Hz. The produces 10 beats/second with another tuning fork frequency 265 Hz. The unknow frequency is

A tuning fork A of frequency 256 Hz when sounded with tuning fork B of unknown frequency produces 4 beats/s. When B is loaded with wax, 6 beats/s were heard. If some of the wax is reduced, the number of beats again reduces to 4 beats/s. Determine the initial frequency of B.
