354986 Two tuning forks \(P\) and \(Q\) when set vibrating, give 4 beats \(s^{-1}\). If a prong of the fork \(P\) is filled, the beats are reduced to \(2 s^{-1}\). What is frequency of \(P\), if that of \(Q\) is \(250\;Hz\)?

354987 A closed organ pipe and an open pipe of same length produce 2 beats/second while vibrating in their fundamental modes. The length of the open organ pipe is halved and that of closed pipe is doubled. Then, the number of beats produced per second while vibrating in the fundamental mode is

354988 The string of a sonometer is divided into two parts using wedge. Total length of string \(1\;m\) and the two parts differ by \(2\;mm\). When sounded together they produce 2 beats \(/ \mathrm{sec}\). The frequencies of two parts are

354989 Two tuning forks \(A\) and \(B\) sounded together give 6 beats per second. With an air resonance tube closed at one end, the two forks give resonance when the two air columns are \(24\;cm\) and \(25\;cm\) respectively. Calculate the frequencies of forks.
