After the module is still, the pressure on the bottom of the cup will be (the buoyancy on the wooden block will be ((select "increase", "unchanged" or "decrease") and explain the reason (more details), Some people say that the depth will not change after adding salt, but I think the depth should decrease. Second, I understand,

8. Pressure and buoyancy 20. (09 Ningbo) as shown in the figure, there is a certain amount of water in an inclined cylindrical container. There is a 5N ball floating on the surface of the container. If the ball is taken out, the decrease of water pressure on the bottom of the container is () A. Greater than 5N B. equal to 5N C. Less than 5N D. It depends on the size of the ball
9. In the center of a square horizontal table with an area of 0.3 square meters, there is a circular container filled with alcohol. The density of alcohol is 0.8 * 10 & sup3; kg / M & sup3;, and the bottom area of the container is 500 square centimeters. Now put a small solid ball with a mass of 0.9 kg and a density of 0.9 * 10 & sup3; kg / M & sup3; into the container Judge whether the ball floats, floats or sinks into the container after it is forbidden? What is the buoyancy of the ball at this time? 84n, I also count 8N Is the land area in the condition useless? Does it have anything to do with that depth? But the answer is 7. This is an exercise in the universal thinking training program. Our teacher only talks about the results, so I have to teach myself.
