What type of equipment do you need to play curling? a broom and a stone a metal ball and a wooden ball a net and a rattan ball a rubber ball and a wooden bat

I'm not super sure but, I would think it would be a broom and a stone. When you play curling you push a special 'curling stone' across a icy floor and special sweepers to reduce the fiction within the icy floor.

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.
