The nucleus is the center of an atom.
Scientist identify the process in which gravity pulled materials together forming the planets in our solar system as accretion.
Accretion is the formation model of planets in our solar system in which gravity pulls materials together forming the planets.
This formation model accounts for the formation of the inner planets made of of dense material such as iron. These planets include Mercury, venus, earth etc.
As the gravity pulls in the more dense material, the less dense material such as ice, liquid and gas colect together to form the outer planets, which include Jupiter, Uranus, etc.
So, Scientist identify the process in which gravity pulled materials together forming the planets in our solar system as accretion.

Equal parallel resistors are governed by the formula
R = r^2/(2r) = r/2
r = 2.30 * 10^-8 ohms which is very tiny.
R = 2.30 *10^-8 / 2
R = 1.15 * 10^-8 ohms. <<<< Answer
Answer:
Explanation:
charge transferred to sphere = 12 - 8 = 4 nC
a )
The positive charge is decreased on glass rod , that means electrons must have entered the glass rod from the sphere which reduces its positive charge.
b )
charge transferred = 4 nC = 4 x 10⁻⁹ C
charge on one electron = 1.6 x 10⁻¹⁹ C
No of electrons transferred
= Total charge transferred / charge on one electron
= 4 x 10⁻⁹ / 1.6 x 10⁻¹⁹
= 2.5 x 10¹⁰ .
