can someone help one these questions? https://media.cheggcdn.com/media%2F1c0%2F1c002231-46f6-4647-b39a-8f91805715ae%2FphptOLg72.png

An object with higher moment ot' inertia requires (choose one) more less torque to give it a specified angular acceleration. You have learned that F = ma for linear motion. Write the analogous equation for rotational motion. True or false? "The moment of inertia is always the same for an object, no matter where the axis of rotation is located." True or false? ''Moment of inertia is a scalar." Refer to Figure 1. The tension force is applied at which radius? radius r radius R The magnitude of a torque is the perpendicular component of the applied force multiplied by the distance between the point where that force is applied and the rotation axis. Use this information and Figure 1 to Write an equation for the torque applied to the disk. Write your equation in terms of r or R, hanging mass m, gravitational acceleration g, and the angular acceleration alpha (NOT in terms of the tension T, moment of inertia I, mass M. or linear acceleration alpha).

Explanation / Answer

1). T = I*alpha => more 2).net torque = I*alpha 3). false 4). true 5). no figure 6). no figure
