Light at an angle of incidence of 44.0 degrees moves from air to a liquid. The observed angle of refraction is 31.4 degrees. What is the index of refraction of the liquid? Identify the liquid (Be sure that your calculator is in degree mode). What is the angle of reflection?

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?
