Why is a scientific theory the most powerful explanation scientists have to offer? a. Many different scientists have added data from their own experiments to build the theory.
b. a theory is the same things as a hypothesis.
c. Scientific theories are usually the work ofa single scientist.
d. Technology is used to provide the experimental data for a scientific theory.

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.
