Question

Pendulum clock generally go fast in winter and slow in summer why

Answer 1

So clock goesfast.ii) In summer the length of the Pendulum increases and its time period increases. So the clockgoes slow. ... Time period of apendulum clock is directly proportional to square root of the length of thePendulum.i) In winter the length of the pendulum decreases and its time period decreases.........i hope help u..........

Answer 2

we know that, T = 2 pie (I / g) ^ 1/2. in summer the length of the pendulum increses due to thermal expansion hence time period increses. the clock thus runs slower. the case is reverse in winter.
