Physics - Wave on String Question with Solution | TestHub

A copper wire is held at the two ends by rigid supports. At 30°C the wire is just taut, with negligible tension. Find the speed of transverse waves in this wire at 10°C ($\alpha =1.7\times 10^{-5}$/°C, $Y=1.3\times 10^{11}$ N/m², $\rho =9\times 10^3$ kg/m³). (answer in $m/s$).
