1. Estimate the number of pounds of mercury it would take to fill your bathtub. List all assumptions and show all calculations.
2. A mountain climber's oxygen tank contains 1 lb of oxygen when he begins his trip at sea level where the acceleration of gravity is 32.174 ft/s2. What is the weight of the oxygen in the tank when he reaches the top of Mt. Everest where the acceleration of gravity is 32.082 ft/s2? Assume that no oxygen has been removed from the tank; it will be used on the descent portion of the climb.
