6. 

Nuclear sizes are expressed in a unit named

[A]. Fermi
[B]. angstrom
[C]. newton
[D]. tesla

Answer: Option A

Explanation:

Fermi - A unit of length equal to 10-15 meter (one femtometer), used in nuclear physics. It is similar to the diameter of a proton.

In details what is tesla~?

Sunil Kumar Mahalik said: (Aug 14, 2015)  
Tesla is the unit of magnetic field intensity.

Kamak said: (Oct 12, 2015)  
What is the conductivity?

Dheenar said: (Oct 21, 2015)  
Tesla is the unit of magnetic flux density.

Flux means without inter mediate (transformer, etc.,) can pass current.

Tesla is greatest scientist in the world.

What is meaning of the phrase fermi and where does it derived?

Shashikant Ak said: (Dec 23, 2015)  
What is the resistance?

Shift said: (May 1, 2016)  
@Shashikant.

The obstructions given to the flow of current is called resistance. Its SI unit is ohm.

Femto is also 10^-15.

Usman Abdullahi Karwai said: (Dec 20, 2016)  
Angstrom ~wave length.
Newton~force.
Tesla~magnetic flux.

Fermi is the answer.
