compare the energy of the ball in the air with the energy of one of the balls on the ground. Explain why the amount, type, and form of the energy might be different or the same.

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
