Acopper
wire, whose cross-sectional area is 1.1 x 10-6
m2has a linear density of 7.0 x 10-3 kg/m and
is sturngbetween two walls. at the ambient temperature,
atransverse wave travels with a speed of 46 m/s on
thiswire. the coefficient of
linearexapansion for copper is 17 x
10-6(c)-1 and young's modulus for copperis
1.1 x 1011 n/m2. what will be the speed of the wave
whenthe temperature is lowered by 14 c? ignore any changein
the linear density caused by the change in temperature.
