Answer 1

Answer:

A product is considered to be elastic if the quantity demand of the product changes drastically when its price increases or decreases. Conversely, a product is considered to be inelastic if the quantity demand of the product changes very little when its price fluctuates.

rate of flow - the amount of fluid that flows in a given time. flow rate, flow. cardiac output - the amount of blood pumped out by the ventricles in a given period of time; "a resting adult has a cardiac output of about three quarts a minute
