The volume of the vacuum chamber is 27.1 ∙ 103 m3. Before emptying the chamber, it is filled with air with a density of 1.25 kg / m3. The pressure in the chamber is 101 kPa. The temperature in the chamber is constant during pumping, and after the pumping, there is only 0.70 kg of air left in the chamber. a) Calculate the temperature of the air in the chamber and the pressure in the chamber after pumping.

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
