If u know that answer i will mark has brainliest

The clear liquid is less dense than the black liquid, which is why it floats on top. If the volume were different, you would visually see more clear liquid than black and vice versa.

The clear liquid is less dense than the black liquid

A. The clear liquid is less dense than the black liquid

Explanation:

Since the clear liquid since on top of the black one it's density is less. Whatever liquid has a higher density will sink to the bottom of the flask.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

the correct answer would be d. hope this !
