Can someone please answer this? im blank​

The answer is d) by requesting advice on science internet sites

Iwould sure like to answer your question but i honestly just don’t know

Global warming was a major concern some people do not care global warming is fake it is not real the percentage of it happening  is slight 

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.
