Show all work and specify the correct answer at the bottom! a conducting bar slides without friction on two parallel horizontal rails that are 50 cm apart and connected by a wire at one end. the resistance of the bar and the rails is constant and equal to 0.10 ω. a uniform magnetic field is perpendicular to the plane of the rails. a 0.080-n force parallel to the rails is required to keep the bar moving at a constant speed of 0.50 m/s. what is the magnitude of the magnetic field? 0.36 t0.10 t0.54 t0.93 t0.25 t

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.
