Answer the following in an experiment to study the movement of a simple pendulum. The following figure shows a ball of mass (g 300) suspended in a thread and moving a simple harmonic motion. By the figure, calculate a. The length of the string (L) of the pendulum if the ball moved with a periodic time of its magnitude (2 s) b- Calculate the return force of the ball in units of (N). C- If the ball suspended by the string is transferred to the surface of the moon ... what will happen to the periodic time: (increases - decreases - does not change)
