20 tuning forks are arranged in increasing order of frequency such that every tuning fork produces 4 beats with previous one. If frequency of last tuning fork is double the first, then the frequency of least tuning fork is?

To reduce the frequency of a tuning fork –

50 tunning forks are arranged in increasing order of their frequencies such that each gives 4 beats/sec with its previous tuning fork. If the frequency of the last fork is octave of the first, then the frequency of the first 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 tuning forks is arranged in ascending order of frequency each tuning fork gives 5 beats s with the preceding one. If frequency of the firs tuning fork is 100 Hz and the last fork is 150 Hz then the number of tuning forks arranged will br

A set of tuning forks is arranged is ascending order of frequencies each tuning fork gives 8 beats/s with the preceding one. If frequency of the first tuning fork is 120 Hz and the last fork is 200 Hz, then the number of tuning forks arranged will be,

When temreture increases, the frequency of a tuning fork

When temperature increases, the frequency of a tuning fork

A set of 24 tuning forks are so arranged that each gives 6 beats per second with the previous one. If the frequency of the last tuning fork is double that of the first, frequency of the second tuning fork is
