Good afternoon,

can you help me with those questions

1.

Activity 1: Calculating Torque With those around you calculate the torque on the three rigid bodies by the given force. 60 N 2 m 1 m 45 N 60 0.5 m 20 NActivity 2: Using Torque 1 With those nearby, if the two torques cancel out, what is the magnitude of the force, F? The force is applied at an angle of 36.90 with respect to the horizontal. 200 N 3 m 450 5 mActivity 3: Using Torque 2 Newton's Law of Rotation With those nearby, answer the following question: A machine part has the shape of a solid uniform sphere of mass 230 g and diameter 4.50 cm. it is spinning about a frictionless axle through its center, but at one point on its equator it is scraping against metal, resulting in a friction force of 0.0200 N at that point. Find its angular acceleration. Let the direction the sphere is spinning be the positive sense of rotation
