How will the boat be affected if it enters a part of the river where the current is moving south
at 2m/s?

Alexander calder's mobiles are an example of motion because it uses forces of wind and water.

How many molecules are present in 3 mols of silicon dioxide (sio2)?

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?
