What does Archimedes' principle state?
💡 Hint: Think of how objects behave in water.
True or False: The center of buoyancy is the centroid of the displaced volume.
💡 Hint: Relate this to how shape affects buoyancy.

A 2 m³ block of wood with a density of 600 kg/m³ is floating in water. Calculate the depth to which the block is submerged. (Density of water = 1000 kg/m³)
💡 Hint: Use the volume ratio based on densities.
An object has a weight of 300 N when submerged in a fluid. If the buoyant force acting on it is 350 N, will the object sink, float, or be neutrally buoyant?
💡 Hint: Compare the weight to the buoyant force to assess floating vs. sinking.
