Blue colour of the sky as seen from earth surface is on the account of scattering of light of shorter wavelength by particles present in the atmosphere of the earth. If the earth had no atmosphere, there would not have been any scattering and sky would have looked dark. When an astronaut is in his spacecraft, he is present above the atmosphere of earth, from where the sky appears dark to him because there is no scattering of light there.

In order to solve this problem, we will have to suppose that the percentage of one of the isotopes in the sample is x, so that the percentage of the other isotope in the sample will be (100 - x). Now :
(i) The mass of {tex}\cdot_8^{16} X{/tex} isotope is 16 u. Suppose its percentage in the sample is x %
(ii) The mass of {tex}\cdot_8^{18} X{/tex} isotope is 18 u. Its percentage in the sample will be (100 - x) %
So, Average atomic mass of {tex}X=16 \times \frac{x}{100}+18 \times \frac{(100-x)}{100}{/tex}
But the avergae atomic mass of X has been given to be 16.2 u. Therefore,
{tex}\begin{aligned}
& 16.2=16 \times \frac{x}{100}+18 \times \frac{(100-x)}{100} \\
& \text { or } 16.2=\frac{16 x+1800-18 x}{100} \\
& \text { or } 16.2 \times 100=1800-2 x \\
& \text { or } 2 x=1800-1620 \\
& \text { or } 2 x=180 \\
& \text { And } x=\frac{180}{2} \\
& \text { or } x=90
\end{aligned}{/tex}
Thus, the percentage of the isotope {tex}\cdot_8^{16} X{/tex} in the sample is 90 %. The percentage of the other isotope {tex}\cdot_8^{18} X{/tex} in the sample will be 100−90=10%

The main difference between a corporation and a non corporation is that a corporation is a separate legal entity from its owners. A non-corporation, on the other hand, ties the business to its individual owners and any actions that take place within the company come with full liability for those who are involved.
