Mr. Bennet's class completed an investigation on magnetism. They found that most metals were attracted to magnets and plastics were not. What will happen if Mr. Bennet's class repeats the investigation?

A most metails would be attracted to magnets and plastics would not.

B plastics would be attracted to magnets and metals would not.

C both metals and plastics would be attracted to magnets.

D neither metals nor plastics would be attracted to magnets.

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.
