Question 1.
What is the principle behind buoyancy?
Show hintHide hint
Think of Archimedes' discovery while swimming.
Question 2.
What does 'center of buoyancy' refer to?
Show hintHide hint
Imagine where that upward push comes from.
3Question 3.
What is the purpose of Archimedes' Principle?
- To explain gravity
- To define buoyancy
- To describe fluid pressure
Show hintHide hint
Recall the principle discovered in a bathtub.
4Question 4.
True or False: A metacenter below the center of gravity indicates stable equilibrium.
- True
- False
Show hintHide hint
Think about which position leads to capsizing.
Question 5.
A boat is designed with a center of gravity 1 meter below the waterline. If the metacentric height is calculated to be 0.5 meters, what does this suggest about the boat's stability?
Show hintHide hint
Visualize the metacenter's position and role in stability.
Question 6.
If a submerged object has a volume of 2 cubic meters and the fluid density is 1000 kg/m3, calculate the buoyant force acting on the object.
Show hintHide hint
Utilize the buoyant force formula you've learned.
