Some of the most buoyant woods are balsa, cork, cedar, cypress, pine, redwood, spruce, mahogany, teak, and fir. These woods are valued for their lightweight and buoyant properties, making them ideal for use in boat building and other water-related applications.
Wood is a poor conductor of electricity due to its high resistance. However, it can still conduct electricity to some extent when wet or when exposed to high voltages. Overall, wood is considered an insulator when it comes to electricity.
The weight would depend on if the desk is made of aluminum, iron, or wood. If wood, it would depend on the type of wood. As one example, pressed wood or particle board weighs more than other natural woods. Some natural woods are heavier than other natural woods, as well.
Yes, theoretically, the impact between two metal objects in the woods would still produce sound waves, even if there is no one present to hear it. Sound is a form of energy that is created by vibrations, so the collision would generate sound waves that propagate through the environment.
Almost every type of wood will float. There are a few very dense and rare woods found in the tropics that will not float. And if formed properly, pretty much anything can be made to float including stone and concrete.
