The force f, of the wind blowing against a building is given by f=cdrhov2 a/2, where v is the wind speed, rho the density of the air, a the cross-sectional area of the building, and cd is a constant termed the drag coefficient. (a) determine the dimensions of the drag coefficient. (b) is this a homogeneous or a non-homogeneous equation? how can you tell? (c) in what unit system is the coefficient defined?

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
