Formula for calculating buoyancy by balance method

Floating: two forces balance f floating = g object
Levitation: two force balance f floating = g object
Sinking: balance of three forces, f floating + F support = g, f floating = G-F support

7. On the physical aspect of XT graph In XT graph, when the line in the graph starts from zero, it moves up first. When it reaches a point, it moves down again. When v reaches zero, it continues to fall below zero. When it goes up, it's a positive speed. I don't know if the zero point is turning around from time to time when I go down. If it's below zero point, it's back to the starting point and moving in another direction Compulsory one in senior one

17. When the law of diminishing marginal returns takes effect, the total cost curve begins to change A. To decline at an increasing rate; B. to rise at an increasing rate; C. To decline at a decreasing rate; D. to rise at a decreasing rate Hello, I'd like to ask why we don't choose B. I think that when the law of diminishing marginal return comes into effect, that is, the law of increasing marginal cost comes into effect. At this time, the cost increases gradually, so the total cost rises at an increasing rate,
