4. Why is increasing the time interval a safer way to land from a fall? a. It decreases the amount of force
b. It increases the velocity
C. It increases the amount of force
d. It decreases the velocity

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.

Hiya!   the answer is areagood-luck!       ʕ•ᴥ•ʔ   

. we do not care the other details; the average velocity is only concerned with the  displacement rather than the  distance traveled. displacement is the change in position, or the "straight-line vector from the initial position to final position".
