what initial mass of 23592u is required to operate a 950-mw reactor for 1 yr? assume that 200 mev is released per per fission and 34% efficiency.

The answer is d) by requesting advice on science internet sites

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.

Answer(b) both involve the use of levers;
