State Archimedes principle.
Archimedes' principle states that when a body is partially or fully submerged in a fluid, it experiences an upward buoyant force that is equal to the weight of the fluid displaced by the body.
To understand how this principle works, you need to know a few things:
1. Buoyant force: This is the upward force exerted by a fluid on an object submerged in it. It is equal to the weight of the fluid displaced by the object.
2. Weight: This is the force exerted by the gravitational pull on an object. It depends on the mass of the object and the acceleration due to gravity.
Based on these concepts, here's how to apply Archimedes' principle:
1. Step 1: Determine the volume of the fluid displaced by the object. This is the volume of the object that is submerged in the fluid.
2. Step 2: Calculate the weight of the fluid displaced. This is done by multiplying the density of the fluid by the volume of the fluid displaced.
3. Step 3: The buoyant force experienced by the object is equal to the weight of the fluid displaced. This means that the upward force exerted by the fluid on the object is equal to the weight of the fluid displaced.
4. Step 4: If the weight of the object is less than the buoyant force, the object will float. If the weight of the object is greater than the buoyant force, the object will sink. If the weight of the object is equal to the buoyant force, the object will be in equilibrium and will neither sink nor float.
So, in summary, Archimedes' principle states that the buoyant force experienced by an object submerged in a fluid is equal to the weight of the fluid displaced by the object.
