According to the formula F floating = ρ GV, in the case of the same drainage volume, it can be seen that the buoyancy received by the iron ball is greater; while the density of mercury is greater than that of both iron and aluminum, the two balls will float on the surface of mercury. At this time, their force balance is equal to their respective

How much buoyancy does a 0.05g stone sink into the water bottom? (g = 10N / kg, pwater = 1.0 × 10 & # 179; kg / M & # 179;)

I don't know the density or volume of the stone, but I only know that the buoyancy must be less than the - 4th power of 5 × 10

Why does the buoyancy increase when the wooden boat is made hollow? Please explain clearly. Has the V row changed its buoyancy

The above three people are wrong. First of all, according to the simplest force analysis, buoyancy is equal to gravity. If something is sinking, it means that buoyancy is less than gravity; when it floats up, it is opposite until it is equal (at this time, it stops on the water surface). As summarized by Aristotle, buoyancy of an object is equal to the gravity of its liquid displacement. The larger the volume is, the smaller the volume is
