Answer:
For comprehension, the question is written properly with options attached below:
plasma that has particles that never collide frequently enough to exchange kinetic energy and never reach a temperature equal to the surroundings is categorized as:
A. a thermal plasma.
B. ionized plasma.
C. low density plasma
D. nonthermal plasma.
The correct answer to the question above is "Option D (nonthermal plasma.)"
Explanation:
Plasma, for example radiant sun are state of matter made up of atoms where the ions move freely, there are composed of photons and free electrons but the positive and negative ions are equal creating a swirling gas of positive ions and negative electron and they are also good conductors of electricity as their charged particles move.
Unlike thermal plasmas that ensure their temperature is equal to their surroundings, non-thermal plasma, is not in equilibrium with its surrounding., in other words, non-thermal plasma never reaches temperature that is equal to their surroundings. They can be formed by electrifying electromagnetic waves.

Easy ive done this brings back memories
Explanation:
(a) It is known that relation between energy and mass is as follows.
where, E = energy
m = mass
c = speed of light = 
m/s
As it is given that mass is 
kg. So, putting the given values into the above formula as follows.
= 
= 
Therefore, we can conclude that the energy produced by the reaction between one electron and one positron is .
(b) When gamma ray photons are produced then they will have the same frequency. Relation between energy and frequency is as follows.
E = 
..... (1)
where, h = plank's constant = 
= frequency
Also, ........ (2)
Hence, equating equations (1) and (2) as follows.
= 
So,
=
= 
Thus, we can conclude that the frequency is .
That is a steep slope for sure, no doubt about it. Hope this helps!
