SUMMARY
The length of a pendulum can be calculated using the formula derived from the period of a pendulum, which is given by T = 2π√(L/g), where T is the period, L is the length, and g is the acceleration due to gravity (approximately 9.81 m/s²). For a pendulum with a period of 1.2 seconds and a weight of 12.0 N, the length can be determined by rearranging the formula to L = g(T/2π)². Substituting the values, the length of the pendulum is approximately 0.36 meters.
