What's true about the elliptical path that the planets follow around the sun? a. a line can be drawn from the planet to the sun that sweeps out equal areas in equal times. b. a line can be drawn from the planet to the sun that follows the same curve as the ellipse. c. a scalar can be measured from the angle that the planet travels relative to the sun's orbit. d. a vector can be drawn from the center of one planet to the center of an adjacent planet.

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.
