Which of the following best explains why lightning occurs? (Sorry about the subject, physics does not seem to have any people answering questions for it)
A: The warm updraft heats air molecules to extreme temp
B: Positive and Negative ions build up and need to discharge
C: High pressure storms condense air into a high energy state
D: Thunderstorms pull energy up from earth to sustain themselves
b Is your answer
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash
Hope this helps :p
I hope b is the answer :/

Using a system of elimination is easy:
Bring the two equations up.
[tex]-6x + 9y = -12\\8x - 9y = -8\\[/tex]
Since we have 9y and -9y, they cancel each other out.
We now have:
[tex]-6x = -12\\8x = -8\\[/tex]
Now solve for x.
1. x = 2
2. x = -1.
