Question: A copper wire, whose cross-sectional area is 1.1 10-6 m2, has a linear density of 9.8 10-3 kg/m and is strung between two

A copper wire, whose cross-sectional area is 1.1 × 10-6 m2, has a linear density of 9.8 × 10-3 kg/m and is strung between two walls. At the ambient temperature, a transverse wave travels with a speed of 46 m/s on this wire. The coefficient of linear expansion for copper is 17 × 10-6 (C°)-1, and Young's modulus for copper is 1.1 × 10-1 N/m2. What will be the speed of the wave when the temperature is lowered by 14 C°? Ignore any change in the linear density caused by the change in temperature.
