The electromagnetic force is responsible for the electrostatic attraction and repulsion between charged particles and since the protons have positive charge and electrons have negative charge so the electromagnetic force will be the fundamental force primarily responsible for the attraction between electrons and protons
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.

Excited state , as stated in quantum mechanics
Answer:
42 days
Explanation:
Half life = 8.4 days
Starting mass = 40.0 g
Time = ?
Final Mass = 1/16 * 40 = 2.5 g
First Half life;
Remaining mass = 40 / 2 = 20g
Second Half life;
Remaining mass = 20 / 2 = 10g
Third Half life;
Remaining mass = 10 / 2 = 5g
Fourth Half life;
Remaining mass = 5 / 2 = 2.5g
Time = Number of half lives * Duration of half life = 5 * 8.4 = 42 days
Answer:
Answer below!!
Explanation:
The volume of a gas is inversely proportional to presure keeping the temperature the same.
