The radius of Mercury's orbit is r = 5.79 x 1010 m and its orbital period is T = 88 days. What is the magnitude of the orbital velocity for the planet around the sun, assuming a circular orbit?

Ithink the answer is c but then again i'm probably wrong

Answer8.0m;

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.
