If you hold a sheet of paper vertically and blow air just to the left side of the paper, the paper will

A. stay as it is because nothing has changed.

B. moves to the left because the air pressure on the left side of the paper is less than on the right.

C. moves to the right because the air pressure on the right side of the paper is less than on the left.

D. moves to the left because the air pressure on the left side of the paper is more than on the right.

E. moves to the right because the air flow becomes turbulent on the right side of the paper.

E. moves to the right because the air flow becomes turbulent on the right side of the paper.

anonymous · Answer

If you blow parallel to the left side of the paper, Bernoulli effect will make the paper go left, as the high-velocity air has lower air pressure than the air on the right side of the paper.
