C) Newton D) Tesla

Answer 1

Question :-

Nuclear sizes are expressed in a unit named ↓

Answer :-

Nuclear sizes are expressed in a unit is called "Fermi" .

This is a unit of length .

One metre = 10^{15} Fermi

Or ,

→ 1 Fermi = 10^{-15} metre .

1 Fermi is smaller then the diameter of a proton .

Answer 2

Explanation:

Explanation: Nuclear sizes are expressed in a unit called "Fermi" which is a unit of length equal to 10−15 metre (one femtometre), used in nuclear physics. It is similar to the diameter of a proton.
