(a) prove that the change in period P of a physical pendulum with temperature is given by ∆P = 1/2 ∝ PAT. (b) A clock pendulum made of invar has a period of 0.500 s and is accurate at 20ºC. if the clock is used in a climate where the temperature averages 30º C, what approximate corrections to the time given by the clock is necessary at the end of 30days?
