A piece of aluminum foil measures 6.51 cm by 8.34 cm and has a mass 0.383 g. The density of aluminum is 2.70 g/cm3. What is the thickness of the foil in cm

It is d, all the other ones say incorrect answer .

That would be kinetic energy

You would need to take a picture so i can see

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.
