A(n) 22.0-kg solid sphere of radius 1.20 m is being rotated by applying a constant tangential force of 10.0 N at a perpendicular distance of 1.20 m from the rotation axis through the center of the sphere. If the sphere is initially at rest, how many revolutions must the sphere go through while this force is applied before it reaches an angular speed of 27.0 rad/s

The total amount of energy contained in an object

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.
