that's changed by the experimenter and impacts the dependent variable.<span>
</span><span>An
independent variable is a variable in which you can manipulate or control while
the dependent variable depends on the independent variable. An
example of an independent variable is the running while the dependent variable
is your pulse rate. The pulse rate depends on how fast and how long is the
distance of your run. The pulse rate maybe higher and faster if you’ve run quite
long and will be close to stable if you only run for a short distance and slow
speed.</span></span>
Answer:
Lightning
Explanation:
The term plasma referred to that condition when the electrons are "freed" from their host atoms for a short time. It happens due to the high temperatures.
Lightning is a plasma because when a column of electrons moves from sky to ground, the air that it passes through lights up with energy. What we see as lightning is the air. In this air, the electrons are excited and giving off light. We see it as a light.
From this brief discussion, we can say that as electrons become free and become excited and then give light, lighting is a plasma.
