On Earth. Theoretical study. With a perfect liquid (no viscosity). A bubble in a column of liquid is moving up, the column is on a table, I have some questions:
1/ the force on the table increase/decrease when bubble is moving up ?
2/ the center of gravity of {column+liquid} is always the same when the bubble moving up ?
