Answer: Longitudinal waves
Explanation: For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal. Longitudinal waves are waves in which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport
We can calculate the width/thickness of a coin using a screw gauge by placing it in between the teeth of the gauge.
<h3>How we can calculate the thickness using screw gauge?</h3>
We can determine the width/thickness of a coin by using a screw gauge because screw gauge is an instrument that measures thickness of an object that are very thin. First we can placed the coin in between the teeth of the gauge and then move the gauge until the coin can be held tightly. After that note the reading on the scale.
So we can conclude that we can calculate the width/thickness of a coin using a screw gauge by placing it in between the teeth of the gauge.

The work done by the rope on the box is equal to:

where F is the force applied by the rope, d the distance covered by the box and

is the angle between the direction of the force and of the displacement.
Using the data of the problem:

,

and

, we find the work:
P is disproportional to t, which means that if P increases with x factor, the t will decrease with the same x factor. If t increases then P decreases
