Densiry of Water is 1g/CM 3 and the liter of water weighs 1KGberkeman said:
Correct. So how can you use that and the concepts of Buoyancy to answer this set of questions?ztf24 said:
I guess I'm lost. I don't even know if need an equation for this problem. My guess is the buoyancy force is greater when the bottle is filled with water, and not air.berkeman said:Correct. So how can you use that and the concepts of Buoyancy to answer this set of questions?

There's an upward net force on the bottleberkeman said:
BTW, I missed this before. The mass of 1L of water is 1kg. To get the weight in Newtons, you need to multiply the mass by the acceleration of gravity. Makes sense?ztf24 said:
Buoyant force is the upward force exerted by a fluid on an object that is partially or completely submerged in the fluid. It is also known as Archimedes' principle.
Buoyant force is calculated by multiplying the density of the fluid, the acceleration due to gravity, and the volume of the fluid displaced by the object.
Some common examples of buoyant force include why objects float in water, why hot air balloons rise, and why helium balloons float in the air.
The shape and density of an object both play a role in determining the buoyant force acting on it. Objects with a greater volume and lower density will experience a greater buoyant force, while objects with a smaller volume and higher density will experience a smaller buoyant force.
Buoyant force has many practical applications, such as in shipbuilding, designing life jackets and other flotation devices, and creating submarines. It is also used in industries such as oil and gas to lift heavy structures to the surface of the water.
