Mike has a plaster replica of the Eiffel Tower in his room. The volume of the plaster in the replica is 0.25 m3. He wishes to make a bigger replica using a scale factor of 5. What is the volume of plaster that he needs for the new replica? 6.25 m3 31.25 m3 1.25 m3 0.05 m3

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.

Where’s the following?

Heat up ? and cool down? well im guessing at this one, plz check it first
