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.

Estimate the schwarzschild radius (in kilometers) for a mini-black hole formed when a superadvanced civilization decides to punish you (unfairly) by squeezing you until you become so small that you disappear inside your own event horizon. (assume that the your weight is 50 kg)

Consider a production line with five stations. station 1 can produce a unit in 9 minutes. station 2 can produce a unit in 10 minutes. station 3 has two identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines. station 4 can produce a unit in 5 minutes. station 5 can produce a unit in 8 minutes. which station is the bottleneck station?
