<u>Answer:</u> The wavelength of an electron is 
<u>Explanation:</u>
To calculate the wavelength of a particle, we use the equation given by De-Broglie's wavelength, which is:
where,
= De-Broglie's wavelength = ?
h = Planck's constant = 
m = mass of electron = 
v = velocity of electron = 
Putting values in above equation, we get:
Hence, the wavelength of an electron is
The statement that is a part of Kinetic Molecular Theory (KMT) is Molecules in a gas move rapidly. That is option B.
<h3>What is Kinetic Molecular Theory (KMT)?</h3>
Kinetic Molecular Theory (KMT) is defined as the theory that describes the physical behaviour of gases.
The Kinetic Molecular Theory (KMT) include the following:
- Ideal gas molecules are constantly moving;
- They have negligible volume;
- They have negligible intermolecular forces;
- They undergo perfectly elastic collisions; and
- They have an average kinetic energy proportional to the ideal gas's absolute temperature.
Therefore, the statement that is a part of Kinetic Molecular Theory (KMT) is Molecules in a gas move rapidly.

B. We are in the cenzoic era so what previously had happen to cause the life we live today was a huge mass extinction.... hope this helps!!
Answer: If the intermolecular forces are weak, then molecules can break out of the solid or liquid more easily into the gas phase. Consider two different liquids, one polar one not, contained in two separate boxes. We would expect the molecules to more easily break away from the bulk for the non-polar case. If the molecules are held tightly together by strong intermolecular forces, few of the molecules will have enough kinetic energy to separate from each other. They will stay in the liquid phase, and the rate of evaporation will be low. ... They will escape from the liquid phase, and the rate of evaporation will be high. To make water evaporate, energy has to be added. The water molecules in the water absorb that energy individually. Due to this absorption of energy the hydrogen bonds connecting water molecules to one another will break.
Hope this helps..... Stay safe and have a Merry Christmas!!!!!!!! :D
