Carbon-14 has a half-life of 5,730 years. If scientists discover a mummified Cro-Magnon specimen, they will first want to determine its age. When examining a sample from the bone remains, the scientists discover the specimen is composed of 12.5% carbon-14 and 87.5% nitrogen-14. How old is this mummy? A. 5730 yrs old
B. 22920 yrs old
C. 11460 yrs old
D. 17190 yrs old

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.
