Answer:
Electrostatic Discharge during the equalization of the separated positively and negatively charged electrostatic charges in the storm clouds.
Explanation:
In nature, lightning occurs during the discharge of the large charges contained in the separated positively and negatively particles in the atmosphere in the process equalizing (neutralizing) of the charges, leading to the release of instantaneous energy in the form of heat, light and sound
During a storm, as the clouds mixes by the wind with different densities, they rub each other forming electrostatic charges. The lighter positively charged particles rise to the top clouds while the heavier negatively charged particles move to the bottom. The charges continue to add up to a point where their magnitudes is large enough such that a big spark or lightening occurs between the positive and negative charges during the process of re-equalization of the charges to revert to neutrality.
Answer:
B. 22,22,23,23,22,22,23
Explanation:
The standard deviation is a measure of dispersion or variability of a data set. In order to determine the data set that has the smallest standard deviation, we shall investigate on the ranges of the data sets given. The range of a data set is simply the difference between the maximum and minimum values in a data set. A data set that has a smaller range also has a smaller standard deviation.
From the alternatives given, the data set given by alternative B has the smallest range and consequently the smallest standard deviation.
The maximum value is 23 while the minimum is 22. The range is 1.
Answer:
z
Explanation:
x repersents a new moon and the others repersent quarter moons
(x is a new moon because new moons are often the phase when the moon is close to earths sun)
To solve this problem we will use the ratio given by the amount of total charge (q) equivalent to the individual charge of each electron (e) multiplied by the total number of electrons (n) present, that is,
Here
q = Total charge
e = Electron charge
Our value of the charge is
We know that the charge in a electron is
Replacing we have then
Therefore the number of electrons needed to form a charge of -2nC is 
Because with a chemical reaction there is usually a new substance being made for example wood burning creates ash
