I'll mark as brainliest if your answer is correct!! #1: A study performed yielded results that indicated the more natural sunlight a person was exposed to, the more likely they were to show increases in serotonin in their bloodstreams. This correlation is an example of a correlation.

#2: researchers were interested to see how many people who break the speed limit could be deterred from their bad behavior. Upon observation, they noticed that the more often and frequent law enforcement appeared at Highway stops the less likely people were to speed in that area. This correlation is a great example of a correlation.

In a thunderstorm, charge builds up on the water droplets or ice crystals in a cloud. thus, the charge can be considered to be distributed uniformly throughout the cloud. for the purposes of this problem, take the cloud to be a sphere of diameter 1.00 kilometer. the point of this problem is to estimate the maximum amount of charge that this cloud can contain, assuming that the charge builds up until the electric field at the surface of the cloud reaches the value at which the surrounding air breaks down. this breakdown means that the air becomes highly ionized, enabling it to conduct the charge from the cloud to the ground or another nearby cloud. the ionized air will then emit light due to the recombination of the electrons and atoms to form excited molecules that radiate light. in addition, the large current will heat up the air, resulting in its rapid expansion. these two phenomena account for the appearance of lightning and the sound of thunder. take the breakdown electric field of air to be eb=3.00ă—106n/c. part a estimate the total charge q on the cloud when the breakdown of the surrounding air is reached. express your answer numerically, to three significant figures, using ďµ0=8.85ă—10â’12c2/(nâ‹…m2) .
