Imagine you are lifting a box that require 60 in a force to lift you must lift it to the top of this inclined plane your buddy suggest that you pushed the box up the inclined plane instead of lifting it how will the force change if you push the Box instead of lifting it

What are the applications of electromagnetic waves

What are atoms of the same element with varying number of neutrons

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.
