Use the factorial operation to evaluate 4!. 4 x 3 x 2 x 1 4 + 3 + 2 + 1 4.321 4 - 3 - 2 - 1

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.

Good moring let me you on this question the answer the electric force  have a good day ; )

Ithink the answer is c. make unnecessarily  wide gestures
