Question

A curtain is hanging at the entrance of a room. A long corridor runs at right angles to the door, that is parallel to the curtain. If a strong wind blows along the corridor, the curtain will

Options

• get pushed inside the room.

• get pushed outside the room.

• get collected towards one end/swirled.

• remain unaffected.

Answer 1

get pushed outside the room.

Explanation:

Because high-speed winds have low pressure due to particle scattering, and because one side of the curtain has low pressure and the other side has high pressure, the winds will flow from the high-pressure area to the low-pressure area in order to maintain balance, as we already know, and thus the curtain will be pushed in the direction of the high-pressure wind.
