It's about the weight of the fluid pushed aside.
What is buoyancy?
Think about the force acting against gravity.
True or False: Archimedes’ Principle applies only to liquids.
Consider what happens in gases.
A solid cube of side length 10 cm and density 700 kg/m³ is submerged in water. Calculate the buoyant force acting on it.
Use density to find the weight of the displaced water.
A submersible weighs 1200 N when in air and loses 400 N of weight when submerged. Calculate the weight of water displaced and whether the submersible will float.
Compare the weight of the submersible with the weight of the displaced water.
