Consider a venturi with an inlet-to-throat area ratio of LaTeX: 1.501.50, mounted on the side of an airplane fuselage where the local air density is LaTeX: 1.225 mathrm {kg/m^3}1.225 k g m 3. A manometer is connected to the inlet and the throat; the height difference of the liquid is seen to be LaTeX: 12.5 mathrm {cm}12.5 c m. The manometer uses mercury, which has a density of LaTeX: 1.36 times10^4 mathrm {kg/m^3}1.36 × 10 4 k g / m 3. However, at this altitude gravity is only LaTeX: 95 % of the gravity at Earth's surface. What speed is the airplane flying at?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
