A student measures the time T for one complete oscillation of a pendulum of length l. Her results are shown in the table. l/m: 0.420 ± 0.001, T/s: 1.3 ± 0.1 She uses the formula T = 2π√(l/g) to calculate the acceleration of free fall g. What is the best estimate of the percentage uncertainty in the value of g?
