# What will be the speed of the wave when the temperature is lowered by 14.3 Co? [closed]

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.

 Welcome to Phsics.SE. Our FAQ forbids us to answer things that look like problems from elementary homework exercises. However, all is not lost, there is a meta question which gives some guidance that may help you to ask elementary conceptual questions which we will answer. – dmckee♦ Nov 8 '12 at 4:10
