The same wooden block is first lowered onto the surface of the water and then onto the surface of kerosene.
a) Does the same Archimedes force act on a bar in water and in kerosene?
b) In what liquid is the bar immersed deeper?
a) The same: in both cases, the force of Archimedes is equal in magnitude to the force of gravity acting on the bar, b) In kerosene, the bar is immersed deeper, because the density of kerosene is less than the density of water, respectively, and the force of Archimedes will be less.
