You have just measured the length of earthworms collected in the schoolyard. The next step in this activity is to find the average length of the worms. What is the quickest way to accomplish this task?
A)
Use a calculator to compute the average.
B)
Use the AVERAGE function in the spreadsheet.
Use the Data - Sort function in the spreadsheet.
D)
Do the mathematical operation to find the average by hand.

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.
