An underwater observation room at an offshore oil rig has a 50-cm diameter window. the center of the window is located at a depth of 6 m below the water surface. the specific gravity of sea water is 1.028. determine a) hydrostatic force acting on the window and b) the location where the force is acting (center of pressure).

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. (refer to the walk-through video to locate the online lab within the online textbook).
