Abicycle is traveling north at 5.0 m/s. the mass of the wheel, 2.0 kg, is uniformly distributed along the rim, which has a radius of 20 cm. what are the magnitude and direction of the angular momentum of the wheel about its axle?

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.

If its history of, then b) because a) implies only present day (now)
