Given the displacement vectors A = (8.00 î − 9.00 ĵ + 5.00 ) m and B = (7.00 î + 5.00 ĵ − 3.00 ) m,
find the magnitudes of the following vectors and express each in terms of its rectangular components.
A) C = + || = m = ( î + ĵ + ) m
B) D = 2 - || = m = ( î + ĵ + ) m

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?

Which object is most likely represented by a dot?

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j
