PLEASE HURRY A wooden block of mass 0.200 kg is given an initial velocity up an aluminum ramp set at a 21° angle above the horizontal. The coefficient of kinetic friction between the wood and the ramp is μ =0.19 and the coefficient of static friction is μ=0.25. Determine the magnitude of the acceleration of the wooden block while it is sliding up the ramp.

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.
