Huh, can't you float a thumbtack in water? If it sinks, it means that the amount of water displaced weighs less than the tack.
A banana has the greater mass of the two, unless the thumbtack is made of something extremely dense, like neutronium.
A thumbtack is typically denser than water so it would sink if placed in water. However, if the surface tension of the water is strong enough, a thumbtack might be able to "float" on the surface, supported by the surface tension.
alligators live longer because they are larger and longer and has a larger part of everything than a crocodile

Pushpins sink because they are denser than water. The pushpin's material, usually metal or plastic, is heavier than water, causing it to sink when placed in water.
It means nothing. Everybody has a body part that is bigger or longer than the other. Knowbody's perfect
A thumbtack is a small nail with an unusually large head, that is designed to be pushed into place by a thumb, rather than by a hammer, as would be done with a regular nail. Thumbtacks are normally used to hold pieces of paper in place, on a cork board, wall, etc.

A line extends forever into space and a line segment is a segment or part of a line, so a line is longer than a line segment.
It depends on what kind of flower you're talking about. There is no reason that one of the sex organs would always be longer than the other.
The thumbtack sinks while the paper clip floats due to differences in their density and shape. The thumbtack is denser than water and has a shape that allows it to displace less water relative to its weight, leading to a net downward force. In contrast, the paper clip, although also made of metal, has a shape that allows it to displace enough water to generate an upward buoyant force that exceeds its weight, enabling it to float.
