Apolarized light beam, with a 7.55 mm diameter circular cross section, is perpendicularly incident on an ideal polarizer, serving as an analyzer. the intensity of the light is 3.87 kw/m2 and the angle between the beam's polarization direction and the polarization axis of the polarizer is 19.9∘. what force in piconewtons does the light exert on the polarizer?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?
