The time period (T) of a simple pendulum is given by the formula T = 2π sqrt(L/g), where L is the length of the pendulum and g is the acceleration due to gravity. The length of the pendulum is the length of the wire. Materials expand when heated due to thermal expansion.
The time period of a simple pendulum made using a thin copper wire of length L is T. Suppose the temperature of the room in which this simple pendulum is placed increases by 30°C, what will be the effect on the time period of the pendulum ?
