Consider the video tutorial you just watched. suppose we repeat the experiment, but this time place the divider closer to one side of the tube than to the other. how will the speed of the air on the wide and narrow sides of the divider compare? (assume that burning has a negligible effect on the mass of the air circulating through the tube

Awelder using a tank of volume 7.50×10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×10^5 pa and temperature of 37.1 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 ∘c, the gauge pressure of the oxygen in the tank is 2.00×10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.
