A copper wire is held at the two ends by rigid supports. At 30∘C the wire is just taut, with negligible tension. The speed of a transverse wave in this wire at 10∘C is x m/s. The value of x is [Give your answer as nearest integer value][Given Young modulus of copper=1.3×1011 N/m2,Co-efficient of linear expansion of copper =1.7×10−5∘C−1,Density of copper =9×103 kg/m3] |
