SUMMARY
This discussion addresses conceptual questions in fluid mechanics, specifically focusing on the waterproofing effect of wax on cloth, the apparent weight of a weightless balloon filled with water, and the impact of a man drinking water from a pond on the water level. The waterproofing occurs due to the hydrophobic properties of wax, which repel water. The apparent weight of the balloon remains unchanged when submerged, as it displaces an equal volume of water. Lastly, when the man drinks water, the net level of the pond remains unchanged since the water consumed is already part of the pond's volume.
