U will be marked as Brainliest if u solve 2 and 4 and 5 only U can solve only 1 of them and u will still be marked as Brainliest if ​

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.

Amagnetic field "does not" interact with stationary electric charges. so, a.hope my answer you : )

Simple, don't do it. just don't go to that dock
