Which statement about models is NOT correct? a. Models describe only part of reality. b. Models help build hypotheses. c. Models help guide experimental design. d. Models manipúlate a single variable or factor in an experiment

So what is the question

You would need to take a picture so i can see

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.
