Determine if the following physics statement is true or false:
"Pascal's principle implies that the absolute pressure inside an open swimming pool is exactly identical at the shallow steps and the deep floor."
Correct Answer
false
Explanation
Pascal's principle deals with an *added* external pressure traveling uniformly through a fluid. It does not eliminate the preexisting hydrostatic pressure gradient caused by gravity, which naturally makes the bottom of a body of liquid more pressurized than the top.
