A clock is constructed so that it keeps perfect time when its simple pendulum has a period of exactly 1.000 s. The pendulum bob has length *L* = 0.2486 m and, instead of keeping perfect time, the clock runs slow by 1.502 minutes per day.

(a)

What is the free-fall acceleration (in m/s^{2}) at the clock's location? (Give your answer to at least 3 decimal places.)

m/s^{2}

(b)

What length of pendulum bob (in m) is required for the clock to keep perfect time? (Give your answer to at least 4 decimal places.)
