A vector points -43.0 units along the x-axis, and 11.1 units
along the y-axis.
Find the direction of the vector.

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.?

The momentum of a man riding his bicycle downhill can be calculated. the bicycle and the man have a combined mass of 40 kg. the velocity of the bicycle is 10 m/s. calculate the momentum.
