A building has a flat roof of area 42.0 m^2. Wind blows over the top of the roof at 14.8 m/s. The air inside the building is stationary. What is the difference in pressure (P1-P2) between the two sides of the two sides of the roof? (I got 5934 but that was incorrect)

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 !
