When the suns energy moves through space it reaches earths atmosphere and finally the surface it warms the atmosphere and becomes heat energy then its transfared throughout the planets system by radiation conduction and convection
The electrostatic force between the two ions is ![2.9\cdot 10^{-10} N](https://tex.z-dn.net/?f=2.9%5Ccdot%2010%5E%7B-10%7D%20N)
Explanation:
The electrostatic force between two charged particle is given by Coulomb's law:
![F=k\frac{q_1 q_2}{r^2}](https://tex.z-dn.net/?f=F%3Dk%5Cfrac%7Bq_1%20q_2%7D%7Br%5E2%7D)
where
is the Coulomb's constant
are the two charges
r is the separation between the two charges
In this problem, the ion of sodium has a charge of
![q_1 = +e = +1.6\cdot 10^{-19} C](https://tex.z-dn.net/?f=q_1%20%3D%20%2Be%20%3D%20%2B1.6%5Ccdot%2010%5E%7B-19%7D%20C)
while the ion of chlorine has a charge of
![q_2 = -e = -1.6\cdot 10^{-19}C](https://tex.z-dn.net/?f=q_2%20%3D%20-e%20%3D%20-1.6%5Ccdot%2010%5E%7B-19%7DC)
And the distance between the two ions is
![r=282 pm = 282\cdot 10^{-12} m](https://tex.z-dn.net/?f=r%3D282%20pm%20%3D%20282%5Ccdot%2010%5E%7B-12%7D%20m)
Substituting, we find the electrostatic force between the two ions:
![F=(8.99\cdot 10^9) \frac{(1.6\cdot 10^{-19})(-1.6\cdot 10^{-19})}{(282\cdot 10^{-12})^2}=-2.9\cdot 10^{-10} N](https://tex.z-dn.net/?f=F%3D%288.99%5Ccdot%2010%5E9%29%20%5Cfrac%7B%281.6%5Ccdot%2010%5E%7B-19%7D%29%28-1.6%5Ccdot%2010%5E%7B-19%7D%29%7D%7B%28282%5Ccdot%2010%5E%7B-12%7D%29%5E2%7D%3D-2.9%5Ccdot%2010%5E%7B-10%7D%20N)
where the negative sign simply means that the force is attractive, since the two ions have opposite charge.

<u>Explanation of the properties of electron spin:</u>
Electron spin:
Electron spin is a quantum characteristic of electrons. It is a mode of angular momentum. The magnitude of this angular momentum is perpetual. If the electron spins clockwise on its axis, it is described as spin-up; counterclockwise is spin-down.
- Electron spin has representative s
- The electron spin quantum number has representative ms.
Electron pair:
Electron pair is also known as lewis pair. Lewis pair consists of two electrons that fill the same molecular orbital but have opposing spins. Gilbert N. Lewis introduced the electron pair idea in a 1916 article.

A light bulb lightning up
Explanation:
Answer:
47.48 J/g/K or 4.74 × 10⁴J/Kg/K
Explanation:
C(specific heat capacity)= Q(quantity of heat)/M(mass) × ∆T(change in temperature, Kelvin)
Q= 8000J
M= 46g or 46 ×10^-3Kg
T1= 24°C = 297K
T2 = 28°C = 301K
∆T = 301-297
= 4K
C= 8000/46 × 4
= 47.48 J/g/K or 4.74 × 10⁴J/Kg/K
