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 approx. speed of transverse waves in this wire at 10°C( in m/s). Given ( Young's mod= 1.3*10^-4N/m^2) Coeff. of linear expansion= 1.7*10^-5/°C and density of wire=9*103 kg/m3 .
find d answer..

130 c??? 10 C???is it 10° and 30°? i m assuming that~!
i m getting answer as 7*10-7 m/s
is the answer right?
