You are talking with your friend when all of a sudden a huge lightning storm starts. You and your friend are both amazed by the lightning show.
All of sudden you happen to witness lightning striking the ground. Your
friend says "Wow, that was amazing. We should rush outside to the spot
that the lightning just struck because "lightning never strikes the same
place twice". Now since you are taking Mr De Thomasis class, you know
that although this is a logical statement, it is not necessarily true. Please
explain to your friend why lightning can in fact strike the same place twice.
In your answer. Please include the steps needed to get lightning, as well as
Provide an explanation to correct your friend.

What happens to the velocity of the car when the upward pull of the cable is greater than the downward pull of gravity as the car rises toward the top?

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) .
