>>13450449>hydro bondingget your gay ass chemistry explanations out of here, denser thing go down. If water denser it go below. If thing denser than water it go below water. This applies to all fluids, including air. The least dense fluids (helium, maybe others i dont know too) float to the top of the atmosphere.
>>13450483if the amount of water is constant and the sides shrink inwards whilst the box is kept at the same height, yes the "force" increases as the level of water would increase causing the water to exert an upward pressure as it slides beneath the box because it is denser than the box
if B is a separate initial system from A, and box A is at a stable height, then no because density of water does not change, and the "force" of the denser fluid holding up the lighter object depends on the ratio of densities (which are both constant)
some physics stoodier probably knows the formulas / math behind it if thats what you want
