The separation distance between two 1.0 kg masses is changed. How is the mutual gravitational force affected if separation distance is 5 times the original distance.? (Assume F2 represents the new force and F1 represents the original force.) Choix de groupe de réponses

a. 0.04
b. 1
c. 5
d. 0.25

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.
