Marcie observes a boat floating on water and tries to explain to her mother why the boat is not moving. Which of the following explanations is the best to use? A. The force of gravity acting on the boat is the same as the force of the water pushing up. This means the forces acting on the boat are balanced. B. The force of gravity acting on the boat is the same as the force of the water pushing up. C. This means the forces are unbalanced. The force of the water pushing up on the boat is greater than the force of gravity pulling the boat down. This means the forces acting on the boat are balanced. D. The force of the water pushing up on the boat and the force of the boat pushing itself up allows the boat to float. The two forces are balanced.
