A wooden plug fitted tightly in the vent of a damaged tank may prevent the tank from _______________.
AI Explanation
The correct answer is D) filling completely.
A tightly fitted wooden plug in the vent of a damaged tank will prevent the tank from filling completely. This is because the plug blocks the vent, which is necessary for the tank to take on water and fill up. Without the vent, air cannot escape the tank, which prevents the tank from filling entirely.
The other answer choices are incorrect:
A) collapsing - A plug in the vent would not prevent the tank from collapsing if it is severely damaged.
B) developing free surface moment - A free surface moment is caused by liquid sloshing in a partially filled tank, which would not be prevented by a vent plug.
C) developing free surface - A free surface is the exposed surface of liquid in a partially filled tank, which would not be prevented by a vent plug.
