i understand that an object with smaller density than water will float on water with the same density, it will be submerged and "suspended" in the middle of the water my question is in the case of an object being denser than water, it will sink and finally touches the ground (underwater). i did a quiz 6 months ago and try to recall a question (picture attached) A boat floating on an enclosed pool while a ball of a big density is sinking. When the ball is finally underwater i.e. touches the pool's bottom, What will happen to the water's surface? 1.relative to the bank 2.and relative to the boat I forget what the answer was, can somebody please help? thank you!
