Answer:
The value is ![\Delta s = 8.537 *10^{25 } \ J/K](https://tex.z-dn.net/?f=%5CDelta%20s%20%20%3D%208.537%20%2A10%5E%7B25%20%7D%20%5C%20J%2FK)
Explanation:
From the we are told that
The radius of the sphere is ![r = 6.32 *10^{8} \ m](https://tex.z-dn.net/?f=r%20%3D%20%206.32%20%2A10%5E%7B8%7D%20%5C%20%20m)
The temperature is ![T_x = 5350 \ K](https://tex.z-dn.net/?f=T_x%20%20%3D%20%205350%20%5C%20%20K)
The average temperature of the rest of the universe is ![T_r = 2.73 \ K](https://tex.z-dn.net/?f=T_r%20%20%3D%20%202.73%20%5C%20%20K)
Generally the change in entropy of the entire universe per second is mathematically represented as
![\Delta s = s_r - s_x](https://tex.z-dn.net/?f=%5CDelta%20s%20%20%3D%20%20s_r%20-%20s_x)
Here
is the entropy of the rest of the universe which is mathematically represented as
![s_r = \frac{Q}{T_r}](https://tex.z-dn.net/?f=s_r%20%3D%20%20%5Cfrac%7BQ%7D%7BT_r%7D)
Here Q is the quantity of heat radiated by the star which is mathematically represented as
![Q = 4 \pi * r^2 * \sigma * T^4_x](https://tex.z-dn.net/?f=Q%20%3D%20%204%20%5Cpi%20%2A%20%20r%5E2%20%2A%20%20%5Csigma%20%2A%20T%5E4_x)
Here
is the Stefan-Boltzmann constant with value
![\sigma = 5.67 * 10^{-8 }W\cdot m^{-2} \cdot K^{-4}.](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%205.67%20%2A%2010%5E%7B-8%20%7DW%5Ccdot%20%20m%5E%7B-2%7D%20%5Ccdot%20%20K%5E%7B-4%7D.)
=> ![Q = 4 \pi * (6.32*10^{8})^2 * 5.67 * 10^{-8 } * 5350 ^4](https://tex.z-dn.net/?f=Q%20%3D%20%204%20%5Cpi%20%2A%20%20%286.32%2A10%5E%7B8%7D%29%5E2%20%2A%20%205.67%20%2A%2010%5E%7B-8%20%7D%20%20%2A%205350%20%5E4)
=> ![Q = 2.332 *10^{26} \ J](https://tex.z-dn.net/?f=Q%20%3D%20%202.332%20%2A10%5E%7B26%7D%20%5C%20%20J)
So
![s_r = \frac{2.332 *10^{26}}{2.73}](https://tex.z-dn.net/?f=s_r%20%3D%20%20%5Cfrac%7B2.332%20%2A10%5E%7B26%7D%7D%7B2.73%7D)
=> ![s_r = 8.5415 *10^{25}\ J/K](https://tex.z-dn.net/?f=s_r%20%3D%20%208.5415%20%2A10%5E%7B25%7D%5C%20%20J%2FK)
Here
is the entropy of the rest of the universe which is mathematically represented as
![s_x = \frac{Q}{T_x}](https://tex.z-dn.net/?f=s_x%20%3D%20%20%5Cfrac%7BQ%7D%7BT_x%7D)
=>
=>
So
=> ![\Delta s = 8.537 *10^{25 } \ J/K](https://tex.z-dn.net/?f=%5CDelta%20s%20%20%3D%208.537%20%2A10%5E%7B25%20%7D%20%5C%20J%2FK)

Answer:
Yesssss its 1235 and you are beautiful
Degeneracy pressure arises when sub-atomic particles are packed as tightly as the laws of quantum mechanics allow an object becomes as small as or smaller than Earth.
Answer: Option A
<u>Explanation:
</u>
Degeneracy pressure is the outcome of quantum degeneracy. As stated by Pauli’s exclusion principle, that two electrons of same quantum number cannot occupy the single shell, this leads to compression of shells.
So when the shells are getting compressed, the pressure will be created in the nucleus due to this compression which will be opposing the compression of space of the subatomic particles.
So the more the sub-atomic particles will be packed tightly, the more degenerate levels will be created leading to more compression of size of the atoms even smaller than Earth. This leads to increase in the degeneracy pressure as the interaction will increase between the nucleus and delocalized electrons on decreasing the size of atoms.
Answer: D
Explanation: The chemical bonds in the food store energy that is released when we eat it.
