The level of boat in water is decided by net force on it by gravity (downward) and buoyant force (upward) by fluid. Force of buoyant only depend on volume, density of water and (g) and all these quantities are constant here. So, it remains constant but force of gravity (weight) decreases as mass is decreased W=mg Since downward force decreases and upward force remains the same, a net upward force arises due to brick thrown in water. As a result, the boat will float higher. 5. You have 3 blocks of different densities. Block A has a density PA = 1.5, block B has a density PB = 0.9, and block C has a density of pc = 0.5 cmas a. Do each of the blocks float in water? Water has a density of Pwater cm³ = 1.09 cm² b. Which block would be lowest in the water? Submerged counts as lowest if any blocks sink. C. Which block would sit highest in the water? d. Where would a block with a density of p = 1.0 sit in the water? cm²

Question
The level of boat in water is decided by net force on it by gravity (downward) and buoyant force (upward) by fluid. Force of buoyant only depend on volume, density of water and (g) and all these quantities are constant here. So, it remains constant but force of gravity (weight) decreases as mass is decreased W=mg Since downward force decreases and upward force remains the same, a net upward force arises due to brick thrown in water. As a result, the boat will float higher. 5. You have 3 blocks of different densities. Block A has a density PA = 0.99, and block C has a density of Pc = 0.5 cm3³ 9 cm³° Do each of the blocks float in water? Water has a density of Pwater = 1.0-9 cm³ 1.5, block B has a density PB = b. Which block would be lowest in the water? Submerged counts as lowest if any blocks sink. Which block would sit highest in the water? d. Where would a block with a density of PD = 1.0 = 1.0 sit in the water? cm3
