Question

Q1 The strongest force in nature is,............... .
Q2. The force which binds the nucleons inside the nucleus is.........
Q3write a short note on system of units with special importance to SI system.​

Answer 1

• strong nuclear force

The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature

• Nuclear forces

Nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. They bind protons and neutrons (“nucleons”) into atomic nuclei. The nuclear force is about 10 millions times stronger than the chemical binding that holds atoms together in molecules.

• What are the advantages of SI unit system?

Advantages of SI system of units are: (i) SI is coherent system of units, i.e., a system based on certain set of fundamental units. (ii) SI is rational system of units. i.e., it assigns only one unit to a particular physical quantity.

Answer 2

Answer:

Gravity

Explanation:

Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and gravity.
