Answer:
shielding of electrons
Explanation:
The addition of electrons shells results in the shielding of electrons away from the nucleus, most importantly the nuclear pull resulting from the charge.
- The nucleus pulls electrons to itself due to the net positive charge on it.
- As more electronic shell is added, the effect of the pull weakens outward.
- The inner shell experiences the nuclear pull more than the outer shell electrons.
The effect is responsible for a wide range of properties of elements.
Answer:
Diameter of wire B is 2 times the diameter of wire A
Explanation:
We have given two wire A and B
They are made up of same material and length of both the wire is sane
So 
Let the resistivity of both the wire is 
It is given that wire A has 4 times the resistance as wire B
So 
So 
( As )
So diameter of wire B is 2 times the diameter of wire A
I'd say potential/kinetic energy.
It's known as Absolute Zero. On the Kelvin scale, 0 is the lowest that anything can reach in temperature. It's supposedly impossible to reach, but it's the known limit.
