In a paragraph, explain why humans have so little drinking water available for their use. Be sure to tell at least two details to support your response.

The answer is b.the gaseous state is electrically positive, while the plasma state is electrically negative. 

Iwould say a is accurate

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.

One answer could be erosion
