Question

a boat with bricks is floating on the water. when the bricks are thrown into the water:the level of the water in the pond:

Answer 1

Explanation:

The volume of water is larger than the volume of the brick because the brick is denser than water. Hence, the water level drops

Answer 2

Answer:

The water level around the boat is found to be dropped/lowered.

Explanation:

• Archimedes' principle is a scientific law stating that an object that is completely or partially immersed in a liquid receives an upward force equal  to the weight of the moving liquid.
• When the rock is on the boat, the weight of both the brick and the boat pushes the water down and raises the water level. When the brick is at the bottom of the water, it replaces its volume in the water, not its weight. The density of brick is higher than the  density  of water or volume, so the water level drops.
• Buoyancy is an upward force exerted by a liquid that counteracts the weight of a partially or completely submerged object. In a liquid column, the pressure increases with depth due to the weight of the liquid above. Therefore, the pressure at the bottom of the liquid column  is higher than at the top of the column.
