Justify and use Archimedes's principle of flotation.
Understand the Problem
The question is asking for a justification and application of Archimedes's principle of flotation, which states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object. This principle can be used to explain why objects float or sink in fluids.
Answer
Archimedes' principle states that an object submerged in fluid experiences an upward buoyant force equal to the fluid's displaced weight, determining if it floats or sinks.
Archimedes' principle of flotation can be justified as it states that an object placed in a fluid experiences an upward force (buoyancy) equal to the weight of the fluid displaced by the object. This principle is used to determine whether an object will float or sink. An object will float if its weight is less than or equal to the weight of the fluid it displaces. This is essential for understanding buoyancy in various applications like shipbuilding and scuba diving.

More Information
Archimedes' principle is crucial in various engineering applications, such as designing ships and submarines, which must displace enough water to support their weight. It is also used in determining the buoyancy of objects in fluids and impacts many fields from engineering to physiology.
Tips
A common mistake is confusing the displaced fluid's volume with the object's volume. It's important to remember that it's the fluid's weight that matters for buoyancy.
