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)

Let v1, v2, w be three linearly independent vectors in r 3 . that is, they do not all lie on the same plane. for each of the following (infinite) set of vectors, carefully sketch it in r 3 , and determine whether or not it is a vector space (i.e., a subspace of r 3 ). explain your reasoning

What are the north and south poles of a solenoid change with?

If the pressure in a gas is doubled while its volume is held constant. true or false
