Using data and observations, answer the following questions. Did it seem, that the mass of each 1 cm2 of paper would have the same mass? Explain your response.
How many pieces of 1 cm2 paper would it take to reach the fifth mark on the scale? Show your rationale.
Assume each mark on the scale represented 1 g. Estimate how much a sheet of paper would mass. A sheet of paper is 28 cm by 21.7 cm.
The actual mass of a sheet of copy paper is 4.5 g. What must be the actual mass of a 1 cm2 piece of copy paper? Show your calculations.

Ithink it is c ,i hope i you

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.

Idk just need points
