On a workday the average decibel level of a busy street is 69 dB, with 102 cars passing a
given point every minute.
If the number of cars is reduced to 16 cars
every minute on a weekend, what is the deci-
bel level of the street? Assume that sound in-
tensity is proportional to the number of cars
passing per minute.
Answer in units of dB.

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.
