Several days after snowfall , the roofs of some homes on your street have almost no snow on them, while the roofs on other homes are still covered. assuming they have all received the same amount of sunlight, give one reason for this observation related to thermal energy & insulation.

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.

Answer///(d) atoms contain small,negatively charged particles;

So are u adding some additional catalyst
