Which explanation of the solar system best fits the observations of the planets and how they orbit the sun? (points : 3) the gravity of a large, massive star passing the sun ripped off blobs of material from it that formed the planets.
the planets formed at the center of a collapsing spinning cloud of gas and dust.
the sun and planets formed from a collapsing spinning cloud of gas and dust.
a comet hit the sun and sent off fragments that became the planets.

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.
