Use the fact that the orbit of a planet about the Sun is an​ ellipse, with the Sun at one focus. The aphelion of a planet is its greatest distance from the​ Sun, and the perihelion is its shortest distance. The mean distance of a planet from the Sun is the length of the semimajor axis of the elliptical orbit. See the illustration. The mean distance of planet A from the Sun is 86 million miles. If the aphelion of planet A is 88.5 million​ miles, what is the​ perihelion? Write an equation for the orbit of planet A around the Sun.

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
