A0.200-kilogram ball sits on a shelf 2.00 meters from the floor and then falls to a point 1.00 meter from the floor. ignoring any affects due to friction, at this position its mechanical energy is 3.92 j its potential energy is 3.92 j its kinetic energy is 3.92 j its potential energy is 1.96 j its kinetic energy is 1.96 j its mechanical energy is 1.96 j

Which simple machine is not part of this compound machine? a. lever b. pulley c. inclined plane d. wheel and axle

Explain how the energy of rubber ball is tranforned as it roll down a ramp. give evidence that the energy of the og the ball remains the same at all points on the ramp

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
