A flexible metallic wire at temperature `0^(@)C` has young's modulus Y, length `l` coefficient of thermal expansion `alpha`, volume mass density `rho`. It is clamped between two rigid supports at a distance `l` from each other. If it cools down temperature `Deltatheta` such that a transverse wave can travel through it with speed v. Then
