172724 The speed of sound in an elastic string when it is extended by $\mathbf{x ~ m}$ is $\mathrm{v}$. If it is further extended to $3 \mathrm{x} \mathrm{m}$. the speed of the sound becomes

172725 A second wave frequency $200 \mathrm{~Hz}$ is travelling in air. The speed of sound in the air is $340 \mathrm{~m} / \mathrm{s}$. What is the phase difference at a given instant between two points separated by a distance of $85 \mathrm{~cm}$ along the direction of propagation?

172726 Two vibrating strings ' $A$ ' and ' $B$ ' produce beats of frequency $8 \mathrm{~Hz}$. The beat frequency is found to reduce to $4 \mathrm{~Hz}$ if the tension in the string ' $\mathrm{A}$ ' is slightly reduced. If the original frequency of $A$ is $320 \mathrm{~Hz}$ then the frequency of ' $B$ ' is

172727 Consider a gas with molar mass $M$, if the sound at frequency $f$ is introduced to a tube of gas at temperature $T$ then an internal acoustic wave is set up with nodes separated by $L$. The adiabatic constant $\left(\gamma=C_{p} / C_{v}\right)$ is
