A boat will submerge when it displaces water equal to its own _______...
A boat will float when the weight of the water it displaces equals the weight of the boat and anything will float if it is shaped to displace its own weight of water before it reaches the point where it will submerge. Floating of the boat works on the principle of buoyancy force which is an upward force exerted by a liquid, gas or other fluid, that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus a column of fluid, or an object submerged in the fluid, experiences greater pressure at the bottom of the column than at the top. This difference in pressure results in a net force that tends to accelerate an object upwards.

A boat will submerge when it displaces water equal to its own _______...
Explanation:
When a boat is placed in water, it displaces a certain amount of water equal to its own weight. This is because of Archimedes' principle, which states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces. The boat will continue to float as long as the weight of the water it displaces is greater than or equal to its own weight. However, if the boat displaces less water than its weight, it will sink or submerge.
Displacement of Water:
- The displacement of water refers to the amount of water that is pushed aside or moved out of the way when an object is submerged in it.
- It is directly related to the volume of the object. The volume of an object is the amount of space it occupies.
- When a boat is submerged in water, it pushes aside a volume of water equal to its own volume.
The Role of Weight:
- The weight of an object is the force exerted on it due to gravity. It is equal to the mass of the object multiplied by the acceleration due to gravity.
- In the case of a boat, its weight refers to the force exerted on it due to gravity acting on its mass.
- If the weight of the boat is greater than the weight of the water it displaces, the boat will sink or submerge.
- On the other hand, if the weight of the boat is equal to or less than the weight of the water it displaces, the boat will float.
Conclusion:
The boat will submerge when it displaces water equal to its own weight. This means that the weight of the boat is greater than the weight of the water it displaces. Submergence occurs when the buoyant force (equal to the weight of the displaced water) is less than the weight of the boat.
