A holiday ornament in the shape of a hollow sphere with mass 20x10-2 kg and radius 5.5x10-² m is hung from a tree limb by a small loop of wire attached to the surface of the sphere. If the ornament is displaced a small distance and released, it swings back and forth as a physical pendulum. Part A Calculate its period. (You can ignore friction at the pivot. The moment of inertia of the sphere about the pivot at the tree limb is 5MR2/3.) Take the free fall acceleration to be 9.80 m/s2. Express your answer using two significant figures.
