1. The problem statement, all variables and given/known data 1a)How does a ball floating 50% in water move when a LARGE amount of oil is added? 1b) if something denser than water were added, how would the ball move? 1c) if the exp. was done on the moon with different gravity and no atmosphere, how would the ball move? 2. Relevant equations Fb= PA Fb=gpV 3. The attempt at a solution For question 1a, I believe that the ball would rise because the water would have to exert a greater force when the oil is on top on the ball, since the oil weighs heavier with air. For question 1b, I think that the ball would remain at the same level because the denser substance would just sink to the bottom. For question 1c, I said that the ball would sink because there is less of a buoyant force on the moon. Can anyone tell me if my answers are correct? I'm not sure if I'm thinking of buoyancy in the wrong sense.
