Write the unit of mass in nuclear physics and define it and it is equivalent to how many kilograms?
(N/A) The unit of mass used in nuclear physics is the Atomic Mass Unit,denoted as $amu$ or $u$.
Definition: One atomic mass unit $(1 \ u)$ is defined as exactly $1/12$th of the mass of a carbon-$12$ atom.
Equivalence in kilograms: $1 \ u = 1.660539 \times 10^{-27} \ kg$.
