Monopolies competition in the market.

In a
monopoly, a producer controls the market because it is able to meet the demands of all consumers.

In a
monopoly, a producer controls the market by the authority of the government, and private production cannot take place.

In a
monopoly, a producer controls the market by holding a patent on the process of creating a specific good.

Lake happy times contains 100 km3 of pure water. it is fed by a river at a rate of 50 km3/yr. at time zero, there is a factory on one shore of lake happy times that begins introducing a pollutant to the lake at a rate of 2km3/yr. there is another river that is fed by lake happy times at a rate that keeps the volume of lake happy times constant. this means that the rate of flow from lake happy times into the outlet river is 52km3/yr. in turn, the flow from this outlet river goes into another lake, lake sad times, at an equal rate. finally, there is an outlet river from lake sad times flowing at a rate that keeps the volume of lake sad times at a constant 100 km3 . (a) find the amount of pollutant in lake sad times at the end of 3 months. (b) at the end of 3 months, observers close the factory due to environmental concerns and no further pollu- tant enters lake happy times. how long will it take for the pollutant in lake sad times (found in part (a)) to be cut in half?

A0.5-kg object is connected to a spring that undergoes oscillatory motion. there is friction between the object and the surface it is kept on given by coefficient of friction μk = 0.06 . if the object is released 0.2 m from equilibrium, what is the distance that the object travels? given that the force constant of the spring is 50 n m-1 and the frictional force between the objects is 0.294 n.
