For the answer to the question above, I would say that the Netherlands
was one good example of what are the dangers when creating polders that
are below the sea level. The water always goes where there is a lower
level of the land. That's when the flooding occurs. You can't have a
flood on the mountain. Water will always find its way to lower areas of
land.
First, you must <span>breakdown electric field:
E = 9x10^9 q / R^2
where R is the radius of the cloud
q is the required charge.
So this will come up to a solution of:
q = E R^2 / 9x10^9
= 3 x10^6 x (500)^2 / 9 x10^9
= 83.33 C.
The answer is 83.33 C.</span>
