Which sentence would best introduce this series of events in a descriptive narrative? We found enough buckets, rags, sponges, and soap to wash cars all afternoon. Upon learning that the cost of scout camp had unexpectedly increased, my troop quickly formed a clever plan. Using colorful paint, we created posters to hold by the side of the road that read, "Car Wash Here Today!" When the first car rolled into the lot, we were lined up and ready to start our fund-raising.

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.

45 is the correct answer
