How did niels bohr describe electrons in his atomic moder? their energies can have any values their exact positions cannot be known they have high probability to be found in certain regions. they orbit the central nucleus in discrete paths

Iwannasay c is the most accurate

Iwould say a is accurate

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.
