A bullet with mass 12g and horizontal speed of 70m/s strickes a block of wood 400g and instantly comes to rest with respect to the block. the block is suspended from ceiling by means of thin wiree , calculate the height to the block rises. also estimate the amount of energy Lost!!?

Scientific classification

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.
