Tom is pushing his little sister emily on a sled. Emily has a mass of 30kg and tom is pushung with a force of 10 N. However, there is friction from the sled of 1 N. What is emilys final acceleration? HELP PLEASE!!!

A) acceleration. this seems to be the one that makes sense.

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.
