1.	Why do the pendulum clock run slow in summer and fast in winter?
Answer» Solution :As we know that time period of pendulum CLOCK `T=2pi sqrt((L)/(g))` at a place g and `2pi` are constant so `T ALPHA sqrt(T)` The length of pendulum in summer INCREASES so time period of pendulum is increased So pendulum takes more time to complete one OSCILLATION and clock becomes slow in summer. Vice-versa in winter it becomes fast as time period of pendulum is decreased due to DECREASE in length of pendulum.
