When a sound wave moves past a point inair, what happens to the density of air at thispoint? 1.there is no change in the density of air.2.the density of air increases and thendecreases as the sound wave passes. correct3.there is no air after the sound wavepasses

2.The density of air increases and thendecreases as the sound wave passes.

Explanation:

Sound waves are mechanical waves, which consist of oscillation of the particles in the medium where the wave is transmitted through.

Sound waves are also longitudinal waves, which means that the direction of oscillations of the particles of the medium occurs in a direction parallel to the direction of motion of the wave (so, essentially back and forth).

Due to the nature of longitudinal waves, they create alternating regions of the medium where the density of particles are higher and lower. The former are called compressions, while the latter are called rarefactions.

Therefore, when a sound wave travels through the air, the density of one region of air continuously changes: compression first (high density), rarefaction then (lower density), then compression again, etc..

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
