An airplane flies due north at 200 km/h, and the wind blows in a direction N30°E at 40 km/h. Find the coordinates for the vector representing the resultant for the airplane with the wind factored in, and the resultant airspeed. Show calculation and diagram.

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s.t.p.?
