Question 1.
What happens to the pressure in a fluid as depth increases?
Show hintHide hint
Refers to the formula P = ρgh.
Question 2.
What is the formula for calculating the resultant force on a surface?
Show hintHide hint
Think about how pressure is applied to surfaces.
3Question 3.
What is the relationship between pressure and depth in a fluid?
- Pressure decreases with depth.
- Pressure remains constant.
- Pressure increases with depth.
Show hintHide hint
Refer to the formula P = ρgh.
4Question 4.
Is buoyant force always equal to the weight of the fluid displaced?
- True
- False
Show hintHide hint
Think about how floating objects displace water.
Question 5.
A submerged gate has a pressure of 5 atm at the top and 9 atm at the bottom. Calculate the force exerted on a surface area of 1 m².
Show hintHide hint
Recall that 1 atm = 101325 Pa.
Question 6.
Determine the weight of a body submerged in a liquid with a density of 1000 kg/m³ if it displaces 0.01 m³ of fluid.
Show hintHide hint
Remember the buoyant force is equal to weight of fluid displaced.
