A clock has an aluminum pendulum with a period of 1.000 s at 20.2 °C. Suppose the clock is moved to a location where the average temperature is 28.1 °C. (The linear expansion coefficient for aluminum is 2.20 10-5 °C−1.)
(a) Determine the new period of the clock's pendulum. (Enter your answer to six siginficant figures.)
b)Determine how much time the clock will lose in 2 weeks.
