After brushing fluffy's fur has a charge of +8.0 × 10 -9 coulombs and her plastic brush has a charge of -1.4 × 10 -8 coulombs. if the distance between the fur and brush is roughly 5.0 × 10 -1 meters, what is the approximate magnitude of the force between them?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
