A metallic wire of length `l` is held between two rigid supports. If the wire is cooled through a temperature t. (Y= Young's modulus of elasticity of wire, `rho=` density, `alpha=` thermal coefficient of linear expansion). Then the frequency of oscillation is proportional to

A wire of cross sectional ara A at temmperature T is held taut with negligible tension between two ridig supports . If the wire is cooled to a temperature (T-DeltaT) , what tension is developed in the wire? The coefficient of linear expansion is alpha and the Young's modulus of the wires is Y

A brass wire 2 m long at 27^@C is held taut with negligible tension between two rigid supports. If the wire is cooled to a temperature of -33^@C , then the tension developed in the wire, its diameter being 2 mm, will be (coefficient of linear expansion of brass =2.0xx10^(-5)//^(@)C and Young's modulus of brass =0.91xx10^(11)Pa )
