Prairie dogs are able to breathe inside their tunnels because different wind speeds above the tunnel create a pressure differential that forces air through the tunnel. In this case, the wind speed is \( 9.9 \mathrm{~m} / \mathrm{s} \) at point \( A \) and \( 1 \mathrm{~m} / \mathrm{s} \) at point \( B \). Assuming that the elevation and air density \( \left(1.29 \mathrm{~kg} / \mathrm{m}^{3}\right) \) is the same at these two points, what is the pressure difference caused by the wind speeds? \( P=\quad \) unit Knowing that air flows from high to low pressure, which direction will the air move through these tunnels?
