Question 1 1. Why do objects feel a buoyant force? (Why is it possible for objects to float or rise in water?)

Question 2 2. An object has a mass of 2 kilograms, and a volume of 4 meters cubed. What is the density of the object?

Question 3 3. If the water displaced by an object would have a mass of 40 kilograms, what is the buoyant force on that object?

Question 4 4. Which of the following is a DENSE material?

Question 5 5. A ball is floating, such that 0.2 meters cubed of it is submerged. If the density of water is 1000 kilograms per meter cubed, what is the buoyant force on the ball?
