Energy can be stored in moving objects, and by lifting objects into higher positions Two objects with different masses are lifted up by 3 m.

State how the mass of the object affects the amount of gravitational potential energy stored in it.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?
