Final answer:
The clearance between the bottom of a fire extinguisher and the floor cannot exceed the height of the extinguisher itself.
Step-by-step explanation:
In Physics, the clearance between the bottom of a fire extinguisher and the floor depends on its weight and the force of gravity acting on it. The maximum clearance occurs when the extinguisher is at its heaviest and gravity is pulling it downward with the greatest force. Therefore, the clearance cannot exceed the height of the extinguisher itself.
For example, if the height of the extinguisher is 1 meter, then the clearance between the bottom of the extinguisher and the floor cannot exceed 1 meter.
