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/m^3) blows past the openings at different speeds, as the drawing indicates. (vA = 7.2 m/s, and vB = 1.3 m/s.) Required:
Assuming that the openings are at the same vertical level, find the difference in air pressure between the openings and indicate which way the air circulates.

In what direction does the medium move relative to the direction of the wave? explain.

The built in flash in a compact camera is usally capable of giving correct exsposure for distance up to how many meters?

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
