One part of the carbon-nitroren cvele that provides energy for the sun is the 25 032 u) and the results of this reaction, determine the mass of 1bn in reactionhn+1.943 mev. using the known masses of 1c (12.000 000 000 u) atomic mass units. be careful with your significant figures

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.
