A sound is transmitted through equal lengths of the following materials: air, aluminum, and alcohol. Rank the materials in order, starting with the material through which you will hear the sound first. Write one or two sentences to explain your reasoning. (2 points)

It may possibly be c i think |-/

The answer is a.  i hope this

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.
