A tuning fork vibrates with 2 beats in `0.04` second. The frequency of the fork is

A tuning fork vibrates with 2 vibrations in 0.4 seconds . Its frequency ( in Hz ) is

A given length of sonometer wire is in resonance with a tuning fork. If the length of the wire is reduced by 4% the wire vibration with the fork produces 8 beats per second. The frequency of the tuning fork is

A tuning fork produces 4 beats per sec with one fork of frequency 288 cps. A little wax is placed on the unknown fork and it produces 2 beats per second. The frequency of unknown fork is

A sonometer wire is 31 cm long is in resonance with a turning fork of frequency n. If the length is increased by 1 cm and it is vibrated with the same tuning fork, then 8 beats/sec are heard. The frequency of the tuning fork is -

On vibrating an air column at 627^(@)C and a tuning fork simultaneously, 6 beats/sec are heard. The frequency of fork is less than that of air column. No beats are heard at -48^(@)C .The frequency of fork is

A tuning fork of frequency 100 when sounded together with another tuning fork of unknown frequency produces 2 beats per sec . On loading the second tuning fork , sounded together with first tuning fork , produces one beat , then the frequency of the second tuning fork is

Tuning fork A of frequency 205 Hz produces 5 beats/sec with another fork B. After filing the tuning fork B, it produces 3 beats/sec with A. What was the frequency of the fork B before filling?

Wire having tension 225 N produces six beats per second when it is tuned with a fork. When tension changes to 256 N, it is tuned with the same fork, the number of beats remain unchanged. The frequency of the fork will be
