A submarine is currently being developed to take tourists on sightseeing trips to tropical coral reefs. According to engineering guidelines the sub must be able to withstand a pressure of 10.09 N per square millimeter.
Required:
a. To what depth can the submarine safely descend in seawater?
b. If the submarine is used in freshwater instead, is its maximum safe depth greater than, less than, or the same as the seawater? Explain
