A simple pendulum made of a bob of mass m and a metallic wire of negligible mass has time period 2 s at T=0^oC. 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 then the value of S is :
