If it takes 22 s for a 2.1 N force to move a 1.90 kg bag 1.4 m along a conveyor belt, what is the power output of the motor connected to the conveyor belt?

If forces acting on an object are unbalanced, which factors may result fron an unbalanced force? check all that apply

Could someone me find the answer to this problem.

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?
