Figure shows a physical pendulum constructed from equal-length sections of identical pipe. The inner radius of the pipe is 10.2 cm and the thickness is 6.40 mm.(a)Calculate the period of oscillation about the pivot shown.(b) Suppose that a new physical pendulum is constructed by rotating the bottom section 90° about a vertical axis through its center. Show that the new period of oscillation about the same pivot is about 2% less thanthe period of the original pendulum.
