In the laboratory,a stick 1 m long is pivoted at various points to illustrate the motion of a physical pendulum.A plot of the period versus the distance of the pivot point from the center of mass is shown.The data presented demonstrate which of the following?
A)The motion of a pendulum is circular about the center of mass.
B)The center of mass is at 0.4 m.
C)The graph is meaningless in this form.
D)There is a minimum period in the neighborhood of 1.5 s at a pivotal distance of approximately 0.4 m from the center of mass.
E)The graph should be drawn as a straight line from A to C; point D is obviously wrong.
