Homework Answers
When there is torque on disk angular acceleration will be there because torque T = moment of inertia × angular acceleration.
Angular acceleration caused to change in angular velocity.
Hence last option is most suitable.

To understand how to use conservation of angular momentum to solve problems involving collisions of rotating bodies. (Figure 1) Consider a turntable to be a circular disk of moment of inertia It rotating at a constant angular velocity ωi around an axis through the center and perpendicular to the plane of the disk (the disk's "primary axis of symmetry"). The axis of the disk is vertical and the disk is supported by frictionless bearings. The motor of the turntable is...
