Sound waves are mechanical waves, longitudinal waves, and do no transmit in a vacuum
Explanation:
Sound waves are periodic disturbance of a medium that generates that are produced when a rapid vibration of an object produces a similar periodic vibration in the particles of a medium. Therefore, sound waves are the periodic vibrations of the particles in the medium.
Sound waves are classified as longitudinal waves. Longitudinal waves are those in which the particles of the medium vibrate in a direction parallel to the direction of propagation of the wave: therefore, the particles vibrate back and forth along the direction of motion of the wave.
Sound waves are able to travel through different mediums: gases, liquids and solids. In particular, they travel faster in solids than liquids, and in liquids than gases, because the particles in solids and liquids are closer together, so the transmission of the wave is more efficient.
Sound waves are also classified as mechanical waves, which are waves that transmit through the vibrations of the particles in a medium. For this reason, sound waves cannot propagate if there is no medium: therefore, sound waves cannot propagate in a vacuum.

Explanation:
Metals have few number of electrons in their valence shell.
The force with which the nucleus of the metal atom is pulling the electron towards itself is lower on the valence shell because the distance between the nucleus an valence shell is large.
So,there are a lot of free electrons in metals.
When the ends of metals are at different potential,electrons flow from one end to another to balance the potential.This feature of metals allows them to conduct electricity.
Similarly,when the ends of metals are at different temperatures,conduction will take place and electrons are the carriers of conduction.This feature of metals allows them to conduct heat.
So,metals are good conductors of heat and electricity.
Answer:
Essentially, your thumb is the main piece of your body that has saddle joints. The bones in your seats joint are in charge of moving forward and backward, side to side.
When all is said in done, the piece of the thumb joint that is subjected to extreme anxiety is that known as CMC joint or carpometacarpal joint. This joint is fundamentally shaped by the metacarpal bone and it explains with the trapezium bone of the wrist.
