In a pendulum clock, the pendulum is a metal bar, designed so that its period of oscillation is equal to 1.0 s. It is found that in winter, when the average temperature is 10°C, the clock goes forward an average of 55s per week; in summer, when the average temperature is 30°C, the clock goes backward an average of 1 minute per week. (a) Calculate the coefficient of linear expansion of the metal of the pendulum. (b) At what temperature would the clock run accurately?
