when light passess from air into glass the angle of incidence is always the angle of refraction

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?

Aray of light traveling parallel to the principal axis of a concave mirror will be reflected through the mirror's

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?
