Given two vectors A: 5 meters East and B: 6 meters 30o North of East. What is another way of writing vector A? A) 5 meters 0°
B) 5 meters 90°
C) 5 meters 180°
D) 5 meters 270°

Ithink the answer is c but then again i'm probably wrong

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.

Tons?
