With what minimum speed must you toss a 180 g ball straight up to just touch the 14-m-high roof of the gymnasium if you release the ball 1.4 m above the ground

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.

Ithink the answer is fusion 

It was crowded with sewer like smells. bad sewer systems
