173131 A solid sphere of lithium is rotating with angular frequency ' $\omega$ ' about an axis passing through its diameter. If its temperature is raised by $50^{\circ} \mathrm{C}$ then its new angular frequency is $\left(\alpha_{\text {lithium }}=60 \times 10^{-5}{ }^{\circ} \mathrm{C}^{-1}\right)$

173133 Amplitude of a wave is represented by
$\mathbf{A}=\frac{\mathbf{c}}{\mathbf{a}+\mathbf{b}-\mathbf{c}}$
Then, resonance will occur when

173134 A piston fitted pipe is pulled as shown in the figure. A tuning fork is sounded at open end and loudest sound is heard at open length 13 $\mathrm{cm}, 41 \mathrm{~cm}$ and $69 \mathrm{~cm}$, the frequency of tuning fork if velocity of sound is $350 \mathrm{~m} / \mathrm{s}$, is:

173135 Two tuning forks $P$ an $Q$ sounded together and 6 beats per second are heard. $P$ is in unison with a $30 \mathrm{~cm}$ air column open at both ends and $Q$ is in resonance when length of air column is increased by $2 \mathrm{~cm}$. The frequencies of forks $P$ and $Q$ are
