A pendulum with a 0.3 m length on the moon would have a period equivalent to a pendulum with a 2.0 m length on the earth.Why is a pendulum used?Body suspended from the a fixed point to act as a pendulum that swings back and forth as a result of gravity. Because the period—the amount of time between each full oscillation—is constant, pendulums are employed to control the movement of clocks.The pendulum has what kind of energy?The total of the kinetic and potential energies found in a perfect pendulum system, or mechanical energy, is always present. The ratio of the two types of energy fluctuates continuously as the pendulum swings back and forward between. The pendulum swings with more kinetic energy at various locations.To know more about pendulum visit:https://brainly.com/question/11925465#SPJ4
