Question 1.
What happens to pressure as you dive deeper into water?
Show hintHide hint
Think of what is above you when you go deeper.
Question 2.
What is Pascal's law?
Show hintHide hint
Consider how pressure is applied in a liquid.
3Question 3.
What is the relationship between pressure and depth in fluids?
- Pressure decreases with depth
- Pressure increases with depth
- Pressure remains constant
Show hintHide hint
Think of what happens when you dive deeper.
4Question 4.
True or False: Pressure in a fluid acts in a horizontal direction.
- True
- False
Show hintHide hint
Consider the direction in which pressure is applied.
Question 5.
A diver descends 30 meters in water. Calculate the increase in pressure they experience compared to the surface. (Use ρ = 1000 kg/m³ and g = 9.81 m/s².)
Show hintHide hint
Remember to use the formula P = ρgh for calculating pressure change.
Question 6.
Discuss the design considerations for a dam based on the variation of pressure with depth. Provide examples of how pressure influences structural choices.
Show hintHide hint
Consider what happens to structures under various loads and the reasons for safety factors.
