A grandfather clock is controlled by a swinging brass pendulum that is 1.6 m long at a temperature of 26°C. (a) What is the length of the pendulum rod when the temperature drops to 0.0C? (Give your answer to at least four significant figures.) mm (b) If a pendulum's period is given by T = 2nV L/g, where L is its length, does the change in length of the rod cause the clock to run fast or slow? O fast O slow O neither
