By means of physiological adaptations that are still not very well understood ,sperm whales are thought to be able to hunt for their food at depths of between 350 m and 3100 m. Part A-What range of gauge pressure (in Pa) do the whales withstand at these depths? Part B- What range of gauge pressure (in atm) do the whales withstand at these depths? Part C-Estimate the total inward force of water pressure on the surface of a sperm whale at depth of 3100 m, modelling the whale as a cylinder 18 m long and 4 m in diameter.
