A shipwreck salvage company uses a lifting bag to raise a cannon off the sea bed. The bag is inflated with nitrogen to a volume of 5 m³ at the sea bed pressure of 300 kPa. Assuming no change in temperature, what would the volume of the lifting bag be at sea level where the pressure is 100 kPa?

Two identical stars with mass m orbit around their center of mass. each orbit is circular and has radius r, so that the two stars are always on opposite sides of the circle. (a) find the gravitational force of one star on the other. (b) find the orbital speed of each star and the period of the orbit. (c) how much energy would be required to separate the two stars to infinity?
