Yolanda is studying two waves. The first wave has an amplitude of 2 m, and the second has an amplitude of 3
m.
Which statement accurately describes something that
Yolanda can do as a part of her study?
She can use destructive interference to generate a
wave with an amplitude of 3.1 m.
She can use constructive interference to generate a
wave with an amplitude of 1.5 m.
She can use destructive interference to generate a
wave with an amplitude of 2.8 m.
O She can use constructive interference to generate a
wave with an amplitude of 3.5 m.

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.
