4. On the buoyancy formula of water I've always been confused with F = g and Archimedes principle Take this question for example The submarine begins to dive from the sea until it is completely submerged. In this process, how does the buoyancy of the sea change If f is used in this problem, the buoyancy force should be constant In Archimedes' words, row V becomes larger and row f becomes larger How to judge I'm crazy about buoyancy
5. Buoyancy formula In f-float = g-row = pgv-row, if an object floats or floats, then buoyancy is the gravity of the object. In this case, does g-row refer to the gravity of the object or the gravity of some objects immersed in water? Are the two equal?

13. A spring dynamometer hangs an object and submerges it in water. The indication is 6N. The gravity of draining water is 4N. The gravity of the object is 10N. If it is immersed in kerosene, the buoyancy it receives will be (reduced) Why is it smaller? The density of the liquid decreases, but the volume of the liquid displaced by the object increases. Don't the two counteract each other?
