Question 4. A clock is constructed so that it keeps perfect time when its simple pendulum has a period of 1.00 s at locations where g = 9.80 m/s'. The pendulum bob has length L = 0.2482 m, and instead of keeping perfect time, the clock runs slow by 1.50 minutes per day. a) What is the free fall acceleration at the clock's location? b) What length of pendulum bob is required for the clock to keep perfect time
