Agrandfather clock is controlled by a swinging brass pendulum that is 1.3m long at a temperature of 20°c.
(a) what is the length of the pendulum rod when the temperature drops to 0.0°c?
(b) if the pendulum’s period is given by t = √ / , where l is the length, does the change in length of the rod cause the clock to run fast of slow?
