the two particles that are found in the center of an atom are protrons and neutrons.
Answer:
All of the above
Explanation:
Sound waves are mechanical waves consisting of the oscillations of the particles in a medium. They are longitudinal waves, which means that the vibrations of the particles occur in a direction parallel to the direction of propagation of the wave.
This type of wave consists of alternating regions where:
- the density of the particles is higher: these regions are called compressions, and they correspond to high pressure regions
- the density of the particles is lower: these regions are called rarefactions, and they correspond to low pressure regions
