Answer:
I would got with A or B because they seem more reasonable. Hope this helps and good luck :)
Answer:
according to my calculator
Explanation:
4x+5g=9t
Answer:
Is fire matter? Matter is anything that has mass and occupies space. The flame itself is a mixture of gases (vaporized fuel, oxygen, carbon dioxide, carbon monoxide, water vapor, and many other things) and so is matter. The light produced by the flame is energy, not matter.
Answer:
The average distance is 999.936 light years.
Solution:
As per the question:
Ours is the Milky Way Galaxy with the diameter:
D = 1,00,000 ly
Radius, R = ![\frac{D}{2} = \frac{1,00,000}{2} = 50,000\ ly](https://tex.z-dn.net/?f=%5Cfrac%7BD%7D%7B2%7D%20%3D%20%5Cfrac%7B1%2C00%2C000%7D%7B2%7D%20%3D%2050%2C000%5C%20ly)
Now,
A = ![\pi R^{2} = 50,000^{2}\pi = 7.8539\times 10^{9}\ ly^{2}](https://tex.z-dn.net/?f=%5Cpi%20R%5E%7B2%7D%20%3D%2050%2C000%5E%7B2%7D%5Cpi%20%3D%207.8539%5Ctimes%2010%5E%7B9%7D%5C%20ly%5E%7B2%7D)
The area to each civilization, A' is:
A' = ![\frac{A}{10000} = \frac{7.8539\times 10^{9}}{10000} = 7.8539\times 10^{5}\ ly^{2}](https://tex.z-dn.net/?f=%5Cfrac%7BA%7D%7B10000%7D%20%3D%20%5Cfrac%7B7.8539%5Ctimes%2010%5E%7B9%7D%7D%7B10000%7D%20%3D%207.8539%5Ctimes%2010%5E%7B5%7D%5C%20ly%5E%7B2%7D)
The radius of each area of civilization, r:
![A' = \pi r^{2}](https://tex.z-dn.net/?f=A%27%20%3D%20%5Cpi%20r%5E%7B2%7D)
![r = \sqrt{\frac{A'}{\pi}}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%7B%5Cfrac%7BA%27%7D%7B%5Cpi%7D%7D)
![r = \sqrt{\frac{7.8539\times 10^{5}}{\pi}} = 499.968\ ly](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%7B%5Cfrac%7B7.8539%5Ctimes%2010%5E%7B5%7D%7D%7B%5Cpi%7D%7D%20%3D%20499.968%5C%20ly)
Thus the average separation distance between civilizations is given as:
2r = ![2\times 499.968 = 999.936\ ly](https://tex.z-dn.net/?f=2%5Ctimes%20499.968%20%3D%20999.936%5C%20ly)
Answer: D all of the above
