Una bicicleta tiene 30 cm de radio gira uniformemente a razón de 25 v/min calcular la velocidad angular en Mariales por segundo la velocidad lineal de un punto de la periferia de la rueda

The rearrangement of particles in a physical change. hope this

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.

This question is incomplete and not physics but i'm  willing to if you can give a better question
