A copper wire is held at the two ends by rigid supports. At `60^@C` , the wire is just taut with negligible tension. The speed of transverse waves in this wire at `10^@C` is `x xx 10^1` m/s, what is the value of x.
`(y= 1.6 xx 10^11 N//m^2 , alpha = 1.8 xx 10^(-6)//""^@C " and " rho = 9 xx 10^3 kg//m^3)`
