Read each question carefully and provide your best answer. Show all your work for calculations.
1. Which of the following statements best describes Archimedes' principle?
An object immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object.
The pressure in a fluid increases with depth.
The speed of a fluid increases as its pressure decreases.
All of the above.
2. A block of wood floats in water. This means that the density of the wood is:
Greater than the density of water.
Less than the density of water.
Equal to the density of water.
Irrelevant to whether it floats or sinks.
3. The upward force exerted by a fluid that opposes the weight of an immersed object is called .
4. An object will if its average density is less than the density of the fluid it is in.
5. According to Pascal's principle, a change in pressure applied to an enclosed fluid is transmitted to every portion of the fluid and the walls of the containing vessel.
6. A submerged object displaces a volume of fluid equal to its own volume.
True
False
7. The buoyant force acting on an object depends on the object's mass.
True
False
8. Explain how a submarine is able to submerge and resurface.
9. A solid object has a volume of 0.05 m³ and a mass of 40 kg. Will it float or sink in water (density = 1000 kg/m³)? Justify your answer with calculations.
10. Observe the diagram of Archimedes' screw below. While not directly related to buoyancy, it demonstrates a principle of fluid movement. Describe how this device works.
