1 100g of
bullet with S. H.C 0.03 cal/g°c is intially
at 20°c. It is
fired straightupward with a
Speed of 420m/s and on turning to
its starting point strikes a
cake of ice at
exactly 0°C. How much is melted?

​

Ibelieve the correct answer would be c.

What do you need on

This is the answer: body 1 + engine 2

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.
