Place one polarizing filter on top of a second so you have to look through both of them. Rotate one filer with respect to the other, keeping one stationary. Play around with them until you can answer the following questions. a. How are they oriented with respect to one another when maximum light is transmitted?
b. How are they oriented with respect to one another when no light is transmitted?
c. How is the intensity of transmitted light connected to the angle between the polarizers?

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.

Ibelieve the answer is either b or c, but i'm leaning more towards c.hope my answer has you : )

If your workout exceeds an hour you should substitute "a sports drink" for water.hope my answer has you : )
