Suppose there are three stars in space, each moving at 100 km/s. star a is moving across (i. e., perpendicular to) our line of sight, star b is moving directly away from earth, and star c is moving away from earth, but at a 30° angle to the line of sight. from which star will you observe the greatest doppler shift? from which star will you observe the smallest doppler shift?

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.
