We can use multiple expressions to calculate centripetal acceleration, depending on the physical problem:

Centripetal acceleration with tangental velocity:

a=v²/r, where v is tangental velocity and r is the radius of the circular trajectory.

Centripetal acceleration with angular velocity:

a=ω²r, where ω is the angular velocity and r is the radius if the circular trajectory.

We can calcualte it from the centripetal force Fcp:

Fcp=m*a, so a=Fcp/m, where m is mass and a is the centripetal acceleration.

And also from the equation:

a=√(a₁²+a₂²), where a is total acceleration, a₁ is centripetal acceleration and a₂ is the tangental acceleration, so to get a₁, or centripetal acceleration:

a₁=√(a²-a₂²)

Answer: A. force with which air rushes across the vocal folds

Explanation:

The human voice is produced in the larynx, whose essential part is the glottis. This is how the air coming from the lungs is forced during expiration through the glottis, making its two pairs of vocal folds to vibrate.

It should be noted that this process can be consciously controlled by the person who speaks (or sings), since the variation in the intensity of the sound of the voice depends on the strength of the breath.
