When temperature increases, the frequency of a tuning fork

When temreture increases, the frequency of a tuning fork

To reduce the frequency of a tuning fork –

31 tuning forks are arranged in series in increasing order of frequencies and the frequency of the last tuning fork is 3 times the frequency of the first. If each tuning fork produces 4 beats/second with the preceding one, the frequency of the last tuning fork is

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
