Question

8. Time period of a pendulum varies with its length. True or false? Justify.​

Answer 1

Answer:

Rate of energy transfer do not directly affect time period of a pendulum, energy transfer do affect the velocity of the pendulum, but *average* speed, is the same or around the same, hence a longer travelling distance will have a longer period. The period of a simple pendulum is:2(pi)*sqrt(L/g).
