Answer:
-A screw is an inclined plane wrapped around a cylinder.
Explanation:
<h3>Characteristics: </h3><h3>the length of the stem, battery savers, varied choices on how to clean it thoroughly, the battery replacements, a good sensitivity to heat, and precise readings are the basics that classify thermometers as good-working. </h3>
The radio waves are electromagnetic wave, so it travels with velocity of light i.e 
.
We can use the relation between frequency, wavelength and speed as
Here c is speed of light, 
is wavelength and f is frequency and its value is given 99.90 FM, it is actually in megahertz (i.e 99.90 MHz).
Therefore,
.
Thus, the broadcast wavelength of the given radio station is 3.003 m.

On a velocity - time graph, if the line crosses the x - axis it depicts that the object has started moving in the opposite direction.
