How long is the standard bolt-wrench that comes with most automobiles? how much force would you need to push with in order to move a bolt that requires 250 ftlbs of torque to turn? why is it a good idea to buy a 2ft extension of copper pipe when you get your first car?

Fitness is the ability to perform only very light levels of physical activity.

Sorry i don’t know what to do

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.
