Question:

What happens to the cork after these two steps?

A) 1st step: cork floats horizontally on the water surface, 2nd step: cork floats horizontally on the water surface,

B) 1st step: cork floats completely under the water surface, 2nd step: cork floats horizontally on the water surface,

C) 1st step: Cork floats horizontally on the water surface, 2nd step: Cork floats completely under the water surface,

D) 1st step: cork floats completely under the water surface, 2nd step: cork floats completely under the water surface,

Advice of the day:

In the "floating" condition, the angle of the cork is not important, but only whether it partially protrudes from the water.
