A copper wire, whose cross-sectional area is 5.22 x 10-6 m2, has a linear density of 5.86 x 10-3 kg/m and is strung between two walls. At the ambient temperature, a transverse wave travels with a speed of 43.1 m/s on this wire. The coefficient of linear expansion for copper is 17 x 10-6 (Co)-1, and Young's modulus for copper is 1.1 x 1011 N/m2. What will be the speed of the wave when the temperature is lowered by 14.3 Co? Ignore any change in the linear density caused by the change in temperature.
