A 45 kg rock started rolling from rest to a final velocity of 8.3 m/s in 3.6 seconds. What is the force of the rock? [Hint: Calculate the acceleration first by using the equation a= (V, - V)/t]

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.

Ibelieve the answer is arteries
