In the nature there are four fundamental forces, namely nuclear force, electromagnetic force, weak force, and gravitational force. These forces are arranged with respect to their strengths in descending order.
The nuclear forces are of greater strengths.
These bind up the protons and the neutrons in an atom together. The nuclear forces are strong enough to combine the quarks that form the nucleons.
B= The weak forces of the interaction are the forces that are short ranged and cause the instability of the nucleus. These are 1/10^5 times of the nuclear forces.
C= The electromagnetic forces are the forces that which combine the atoms and the molecules that intend form the ordinary matter. The electromagnetic forces are 1/10^5times of the nuclear forces.
D= The gravitational forces are 1/10^5 times of the nuclear force.
If you have more questions let me know
I would have to say d.Please let me know if i am right.
The correct answer is: D) A and B only
Pneumonia is an inflammatory condition of the lungs that is usually caused by infection with viruses or bacteria. Pneumonia causes the fluid fill of the alveoli (air sacs). As a result symptoms such as cough with phlegm or pus, fever, chills, and difficulty breathing might occur. Pneumonia can be serious condition, especially for infants and people with weakened immune systems.
