The 1.5-m-long brass pendulum of a grandfather clock was manufactured on a day when the temperature was 21C. The coefficient of linear expansion for brass is 19 x 10-6C. (a) What would the length be if the temperature were to increase to 28.0C? (Give your answer to at least 4. decimal places.) m (b) Will the clock gain or lose time due to the change in length of the pendulum? gain time lose time neither gain nor lose time Additional Materials Reading
