Confident answers only please!

A physical pendulum consists of a flat circular disk (the moment of inertia foe the disk about an axis through its center is Idisk = ½ MR2) of mass 2 kg and radium 10 cm. The disk hangs from a nail in the wall such that it rotates about a point on its edge. Using the parallel axis theorem determine the moment of inertia for the disk for rotations about the nail. Write the total energy for the disk as it swings under the influence of gravity (g = 10 m/s2). You may assume the angle of oscillation is less than 30 degree . Identify each type of energy in your expression. Determine the angular frequency and period of small oscillations for the disk. Suppose the disk was made to oscillate about a point closer to
