Two people are attached to each other to go tandem sky diving. Person A has a mass of 72.3 kg, Person B has a mass of 75.4 kg, and the parachute has a mass of 6.0 kg. After several seconds of sky diving and accelerating they open the parachute and eventually reach a slow and steady terminal velocity. Determine the force of air resistance on the sky divers after the parachute opens.

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.
