When temperature increases, the frequency of a tuning fork

When a tuning fork vibrates with 1.0 m or 1.05 m long wire of a , 5 beats per second are produced in each case. If the frequency of the tuning fork is 5f (in Hz ) find f .

16 tuning forks are arranged in increasing order of frequency. Any two consecutive tuning forks when sounded together produce 8 beats per second. If the frequency of last tuning fork is twice that of first, the frequency of first tuning fork is :-

A set of 10 tuning forks is arranged in series of increasing frequency. If each fork gives 3 beats with the preceding one and the last fork has twice the frequency of the first, then frequency of the first tuning fork is

The frequency of tuning forks A and B are respectively 5% more and 4% less than the frequency of tuning fork C. When A and B are simultaneously excited, 9 beats per second are produced. Then the frequency of the tuning fork A (in Hz) is

The frequency of tuning forks A and B are respectively 3% more and 2% less than the frequency of tuning fork C . When A and B are simultaneously excited, 5 beats per second are produced. Then the frequency of the tuning fork A (in Hz) Is

A tuning fork and an organ pipe at temperature 88^@C produce 5 beats per second. When the temperature of the air column is decreased to 51^@C the two produce 1 beat per sec. What is the frequency of the tuning fork?

Length of a sonometer wire is either 95 cm or 100 cm. In both the cases a tuning fork produces 4 beats then the frequency of tuning fork is :-

A tuning fork is vibrating at frequency 100 Hz . When another tuning fork is sounded simutaneously.=, 4 beats per second are heard. When some mass is added to the tuning fork of 100 Hz , beat frequency decreases. Find the frequency of the other tuning fork.

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

There are 26 tuning forks arranged in the decreasing order of their frequencies. Each tuning fork gives 3 beats with the next. The first one is octave of the last. What is the frequency of 18th tuning fork ?
