The correct answer is B. The atomic weight of the element
1) 333.6 C
In order to have breakdown, the electric field at the surface of the cloud must be equal to the breakdown electric field:

The electric field strength at the surface of a charged sphere is given by

where
is the vacuum permittivity
Q is the charge on the sphere
R is the radius of the sphere
Here we have a cloud of radius

So we can re-arrange the previous equation in order to find the charge on the cloud:

2)
excess electrons
The total charge of the cloud must be (in magnitude)
Q = 333.3 C
We know that one electron carries a charge of

The total charge is just given by the charge of each electron multiplied by the number of excess electrons in the cloud:

where
N is the number of excess electrons
Solving for N, we find:

Answer:
22 miles
Explanation:
Answer: False
explanation: because Total momentum is conserved only if the collision can be considered isolated from the influence of net external forces
The correct answer for this question is this one:
<span>A snowstorm was predicted in Chicago. The possible upper air temperature, surface temperature, and air pressure of Chicago on that day. Normal atmospheric pressure is 29.9 inches of mercury. </span><em>I'm pretty sure the answer is 40 for upper air, 29 for surface temp, and 30 for air pressure. </em>Hope this helps answer your question and have a nice day ahead.
