2. As a result of Cthulhu's body heat, the column of ocean water above him has roughly uniform temperature across all depths. According to the ideal gas law, the volume v of the gas bubble escaping his vile aperture will remain inversely proportional to the pressure it experiences as it rises to the surface. In terms of the quantities shown in the figure, this pressure is given by p = Patm + pg(d - y), where patm is atmospheric pressure, so for some constant c. Like the skull, the bubble will exhibit an added mass kv, but its own mass is negligible. In terms of k, p, g, Patm, d, y, and y, find the upward component y of the bubble's acceleration as it rises to the surface. (The quantities y and y appear in this expression because the rising bubble's acceleration - unlike that of the rising skull- 1 will change over time. In principle, one could solve the differential equation relating y and y to y, and find an explicit formula for the bubble's acceleration as a function of time, but this isn't an easy differential equation to solve.) y(t) (meters) 1000- List the units associated with all the quantities appearing in your final answer and make sure the units of your final answer are correct. 3.
