barn
Barn
it is a unit of length that is equal to 10-15meters (one femtometer) which is used in nuclear physics. it is similar to the diameter of a proton.
The newton is the unit of force. The square centimeter is a unit of area; it is unrelated to force. Force / area is force; that's another unit commonly used in physics.
Only for nuclear physics experiments.
No uses, only for nuclear physics experiments
Rutherfordium hasn't practical uses. It used only for nuclear physics/nuclear chemistry researches.
The word barn may mean:A large farm building used for storing farm products and sheltering livestock or a large shed for the housing of vehicles, orA particularly large, typically bare building, orin physics: A unit of area equal to 10 -24 sq. centimeters, used to measure cross sections in nuclear physics.AnswerA unit of nuclear cross section; the effective circular area that one particle presents to another as a target for an encounter.
A fermi is a unit of length - 1x10-15 m or a femtometre. Used in nuclear physics, as it is approximately the diameter of a proton. Named after the physicist Enrico Fermi.

You think to applications of nuclear physics.
What do you mean with "unit of mac"? If you mean "unit of mass", the official unit, used worldwide, is the kilogram.
