Question:
A water bug is suspended on the surface of a pond by surface tension (water does not wet the legs). Th e bug has six legs, and each leg is in contact with the water over a length of 3 mm. What is the maximum mass (in grams) of the bug if it is to avoid sinking?
3 mm 3 mm
Step by Step Answer:
The maximum mass of the bug can be calculated using the force of buoyancy which is the upward force ...View the full answer

The property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules. The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. The molecules at the surface of a glass of water do not have other water molecules on all sides of them and consequently, they cohere more strongly to those directly associated with them (in this case, next to and below them, but not above). is not really true that a \\\"skin\\\" forms on the water surface; the stronger cohesion between the water molecules as opposed to the attraction of the water molecules to the air makes it more difficult to move an object through the surface than to move it when it is completely submersed
