Question

at a given place, since g is constant, the time period of pendulum of given length is constant. this is why a pendulum can be used to measure the time........ . explain the statement...plsssss

Answer 1

the formula of time period​ of simple pendulum is T= 2π√(L/g) since at a given place gravity will always be constant and so will be length that's why pendulum can be used to measure to the time. so the results will always be true
