Prairie dogs are burrowing rodents. they do not suffocate in their burrows, because the effect of air speed on pressure creates sufficient air circulation. the animals maintain a difference in the shapes of two entrances to the burrow, and because of this difference, the air (rho = 1.29 kg/m3) blows past the openings at different speeds, as the drawing indicates. assuming that the openings are at the same vertical level, find the difference in air pressure between the openings.
