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.

Why does a thumbtack sink inwater?

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.


Why does a thumbtack on the water sink?

A thumbtack sinks in water because its density is greater than that of water. While the thumbtack is small and has a pointed shape, it does not displace enough water to create a buoyant force that can counteract its weight. As a result, it cannot float and instead sinks to the bottom.

How did Bourne believe that an object could be made to rise and sink at will?

Bourne believed that an object could be made to rise and sink at will by varying the density of the object to be either lighter or heavier than the surrounding fluid. By adjusting the object's overall weight and volume, it could either float or sink based on the principle of buoyancy.

Why does the thumbtack sink and the paper clip doesnt?

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.
