Q. An object weighs 318 N in the air. When tied to a string, connected to a balance, and immersed in water, it weighs 229 N. When it is immersed in oil, it weighs 261 N.
Q. If the translational rms speed of the water vapor molecules (H2O) in air is 534 m/s, what is the translational rms speed of the carbon dioxide molecules (CO2) in the same air? Both gases are at the same temperature.
