The line width is calculated as 121.6nm
Data;
- Wave length = 393.3nm
- T1 = 3000k
- T2 = 12,000K
<h3>Rydberg's Formula</h3>
This is used to calculate the wavelength of an electron when it moves from one state to another.
For Lyman series, n = 1
The energy difference in the two state transitioning are
= ∞
The formula is given thus;
![\frac{1}{\lambda}= R(1(n_1)^2 - \frac{1}{(n_1)^2}.Z^2\\](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Clambda%7D%3D%20R%281%28n_1%29%5E2%20-%20%5Cfrac%7B1%7D%7B%28n_1%29%5E2%7D.Z%5E2%5C%5C)
R = Rydberg's constant
Z = atomic number
Since the excited electron dropped from the 1st state to the ground state, the finest line of Lyman series would be
![\frac{1}{\lambda} = R(1(1)^2 - \frac{1}{2^2}).1^2\\z=1\\\lambda = \frac{4}{3} * 912A^o\\\lambda = 121.6nm](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Clambda%7D%20%3D%20R%281%281%29%5E2%20-%20%5Cfrac%7B1%7D%7B2%5E2%7D%29.1%5E2%5C%5Cz%3D1%5C%5C%5Clambda%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%20912A%5Eo%5C%5C%5Clambda%20%3D%20121.6nm)

Answer:
200 K
Explanation:
0 °C = 273 K
-73°C = 273 K - 73 K = 200 K
Answer:
a).![Q_{h}=1.5x10^5J](https://tex.z-dn.net/?f=Q_%7Bh%7D%3D1.5x10%5E5J)
b).![Q_{c}=13.2x10^3J](https://tex.z-dn.net/?f=Q_%7Bc%7D%3D13.2x10%5E3J)
Explanation:
a).
Using the law of thermodynamic and using to isovolumetric
ΔU=Qh
![Q_{h}=\frac{W_{net}}{Efficiency}](https://tex.z-dn.net/?f=Q_%7Bh%7D%3D%5Cfrac%7BW_%7Bnet%7D%7D%7BEfficiency%7D)
So to determine the internal energy knowing the work it do
![Q_{h}=\frac{1.5x10^4J}{0.10}=1.5x10^5J](https://tex.z-dn.net/?f=Q_%7Bh%7D%3D%5Cfrac%7B1.5x10%5E4J%7D%7B0.10%7D%3D1.5x10%5E5J)
b).
Efficiency is the work done in relation of the work apply in this case to produce heat so:
![E=\frac{Q_{h}-Q_{c}}{Q_{h}}](https://tex.z-dn.net/?f=E%3D%5Cfrac%7BQ_%7Bh%7D-Q_%7Bc%7D%7D%7BQ_%7Bh%7D%7D)
Solve to Qc
![Q_{c}=Q_{h}*[1-E]](https://tex.z-dn.net/?f=Q_%7Bc%7D%3DQ_%7Bh%7D%2A%5B1-E%5D)
![Q_{c}=1.5x10^4J*(1-0.10)](https://tex.z-dn.net/?f=Q_%7Bc%7D%3D1.5x10%5E4J%2A%281-0.10%29)
![Q_{c}=13.2x10^3J](https://tex.z-dn.net/?f=Q_%7Bc%7D%3D13.2x10%5E3J)
Answer:
Explanation:
The sun keeps all of the planets in orbit around it. Without the sun, all of the planets would fly off into space (out of orbit)
It would have to be a solid so the answer would be A.
