The 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 wooden plug fitted tightly in the vent of a damaged tank would prevent the tank from filling completely. This is because the plug would seal the vent, preventing air from entering the tank as it fills with liquid. Without a vent, the tank would not be able to displace the air inside as it fills, limiting the amount of liquid the tank can hold.
The other options are incorrect:
A) Collapsing - The plug would not prevent the tank from collapsing if it is already damaged.
B) Developing free surface moments - The plug would not affect the development of free surface moments within the tank.
C) Developing free surfaces - The plug would not prevent the development of free surfaces within the tank.
