Show hintHide hint
Think about the weight of the water above you.
Question 2.
State Pascal's Law in your own words.
Show hintHide hint
Consider how a hydraulic lift works.
3Question 3.
What law states that pressure applied to a confined fluid is transmitted equally in all directions?
- Archimedes' Principle
- Pascal's Law
- Bernoulli's Principle
Show hintHide hint
Recall the principle related to hydraulic systems.
4Question 4.

- True
- False
Show hintHide hint
Think about why divers need pressure suits.
Question 5.
A dam has a water depth of 20 meters. If the density of water is 1000 kg/m³, calculate the pressure exerted at the base of the dam.
Show hintHide hint
Use the formula for pressure based on depth.
Question 6.
If two objects of different densities are submerged at the same depth, which will experience a greater buoyant force, and why?
Show hintHide hint
Remember what Archimedes’ principle states about buoyant force.
