Refraction occurs when a wave enters a new medium and changes its speed.
i hope this helps
Answer:
<u><em>Plasma</em></u>
Explanation:
<u><em>Plasma</em></u> is the most common because plasma is a gas that has been energized to the point that some of the electrons break
I'm pretty sure the answer is b 28n hope helps :)
The concept required to solve this problem is linked to inductance. This can be defined as the product between the permeability in free space by the number of turns squared by the area over the length. Recall that Inductance is defined as the opposition of a conductive element to changes in the current flowing through it. Mathematically it can be described as

Here,
= Permeability at free space
N = Number of loops
A = Cross-sectional Area
l = Length
Replacing with our values we have,



Therefore the Inductance is
