<h2>Answer: free electrons</h2>
<u>Plasma</u> is known as the 4th state of matter and is itself ionized gas. In this sense, ionization consists of the production of ions, which are <u>electrically charged atoms or molecules due to</u><u> the excess or lack of electrons</u><u> with respect to a neutral atom or molecule.
</u>
That is why in this process there are always<u> free electrons</u>. Therefore in heating gas to create plasma can yield free electrons, and the correct option is D.
Answer: 
<u>Explanation:</u>
A linear equation is of the form: y = mx + b where
- m is the slope
- b is the y-intercept (where it crosses the y-axis)
x + 4y = 16
4y = -x + 16


The y-intercept (b) = 4
Next, find the slope given point (4, 5) and b = 4

Answer: false
Explanation: because if one car is at 2 m/s and the other at 1 m/s one would be farther away from the stating point
Answer:
140Ns
Explanation:
From Newton's 2nd law of motion
F = ma
F = m∆v/t
==> Ft = m∆v
impulse = Ft = 400 × 0.35 = 140Ns
