Exploring Venus. The surface pressure on Venus is 92 atm, and the acceleration due to gravity there is 0.894g. In a future exploratory mission, an upright cylindrical tank of benzene is scaled at the top but still pressurized at 92 atm just above the benzene. The tank has a diameter of 1.72 m. and the benzene column is 11.50 m tall. Ignore any effects due to the very high temperature on Venus, (a) What total force is exerted on the inside surface of the bottom of the tank? (b) What force does the Venusian atmosphere exert on the outside surface of the bottom of the tank? (c) What total inward force does the atmosphere exert on the vertical walls of the tank?

You are an astronaut exploring a new planet in a distant solar system. This planet has an atmospheric pressure of 1000 mm Hg at sea level. The oxygen content of the planet’s air is 25%. What is the partial pressure of oxygen on this planet at sea level?
In 2085, your company wins a contract to deliver oxygen to several asteroid-based habitats from another asteroid with plenty of oxygen locked up in ice. Since there is no drag in space, the size of the oxygen containers is not an issue, and the most economical method turns out to be to enclose about 6 x 105 kilograms of cold but gaseous oxygen at about half atmospheric pressure in a Mylar sphere 100 m in diameter. To the sphere, you have strapped a small rocket engine. While the engine is firing, the engine presses into the sphere roughly 10 meters, like a finger pushing in on a balloon, as the sphere accelerates. The engine exerts a constant thrust until the sphere reaches its interasteroidal cruising speed of 100 m/s. The sphere travels about 5.0 km while the engine is firing. What fraction of the energy the rocket engine has given to the sphere ends up as internal energy in the gas just before the engine shuts off?
