The pressure of a fluid varies with depth h as P = P0 + ρgh, where ρ is the fluid density. This expression is associated with:
General KnowledgePhysics
- APascal’s law
- BNewton’s law
- CBernoulli’s principle
- DArchimedes’ principle
Explanation
The expression P = P0 + ρgh describes how pressure in a fluid at rest increases with depth, which in this syllabus is associated with Pascal's law. Newton's laws concern motion, Bernoulli's principle concerns moving fluids and Archimedes' principle concerns buoyancy. Hence the answer is Pascal's law.
