A simple pendulum made of bob of mass m ...

A simple pendulum made of bob of mass `m` and a metallic wire of negligible mass has time period `2 s` at `T = 0^(@)C`. If the temperature of the wire is increased and the corresponding change in its time period is plotted against its temperature, the resulting graph is a line of slope `S`. If the coefficient of linear expansion of metal is `alpha` then value of `S` is :

A

`(1)/(alpha)`

B

`alpha`

C

`(alpha)/(2)`

D

`2alpha`

A wooden wheel of radius R is made of two semicircular part . The two parts are held together by a ring made of a metal strip of cross sectional area S and length L. L is slightly less than 2piR . To fit the ring on the wheel, it is heated so that its temperature rises by DeltaT and it just steps over the wheel. As it cools down to surrounding temperature, it process the semicircle parts together. If the coefficient of linear expansion of the metal is alpha , and it Young's modulus is Y, the force that one part of the wheel applies on the other part is :
