A small block of mass M is released from rest at the top of the curved frictionless ramp shown above The block slides down the ramp and is moving with a speed 3.5Vo when it collides with a larger block of mass 1.5M at rest at the bottom of the meline The larger block moves to the night at a speed 2Vo immediately after the collision. Determine the height of the ramp from which the small black was released?​

The answer would be a) -80of

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.
