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.

Concept explainers

Fluid Pressure

The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.

Gauge Pressure

Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

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.
