How does the apparent weight loss of the an object compare with the weight of the water displaced by the object?

The apparent weight loss of an object submerged in water is equal to the weight of the water displaced by the object. This is known as Archimedes' principle.
To understand how to calculate the weight loss and the weight of the water displaced, you can follow these steps:
1. Determine the weight of the object in air: Use a scale to measure the weight of the object when it is not submerged in water. This will give you the actual weight of the object.
2. Determine the weight of the object in water: Submerge the object in a container filled with water and measure its weight. This weight will typically be lower than the weight in air, as the object experiences a buoyant force from the water.
3. Calculate the weight loss: Subtract the weight of the object in water from its weight in air. The result is the apparent weight loss of the object.
4. Calculate the weight of the water displaced: According to Archimedes' principle, the weight of the water displaced by the object is equal to the apparent weight loss. So, the weight of the object in air minus the weight of the object in water is equal to the weight of the water displaced.
By comparing the apparent weight loss of the object with the weight of the water displaced, you can see that they are equal. This principle is useful in various applications, such as determining the buoyancy of objects, understanding flotation, and designing ships and submarines.
