The period T of a simple pendulum is given by T = 2 L/g where L is

The period T of a simple pendulum is given by T = 2π √L/g where L is the length of the pendulum and g is the acceleration due to gravity.
a. Assume g = 9.80 m/s2 exactly, and that L = 0.742 ± 0.005 m. Estimate T, and find the uncertainty in the estimate.
b. Assume L = 0.742 m exactly, and that T = 1.73 ± 0.01 s. Estimate g, and find the uncertainty in the estimate.
