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)

Agroup of monkeys is trying to cross the river in a rowboat. the maximum buoyant force on the rowboat is 2,000 n. the weight of the rowboat is 1,000 n. each monkey has a weight of 150 n. how many monkeys can safely cross in the rowboat at one time? explain your reasoning, including any calculations you used to find the answer.
