What is the equivalent of 15 km/h in meters per second? O 1.8 m/s O 4.2 m/s 5.4 m/s 6.7 m/s

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.

Answer is  true.  because the sensory memory it can also have a fraction of a second before the information is lost. hope it .
