Answer: 1) Angular separation equals 0.0000031 degrees

2) Angular separation in arc -seconds equals 0.011156"

Explanation:

For 2 stars separated by a distance 'S' and at a distance 'D' from the earth the angular separation in radians is given

\theta _{rad}=\frac{S}{D}

Applying values we get

\theta _{rad}=\frac{80\times 10^{6}}{150\times 9.46\times 10^{12}}\\\\\therefore \theta _{rad}=\frac{1}{18487500}radians

Now we know that 'π' radians equals 180 degrees thus the above value in degrees shall be equal to

\therefore \theta _{degrees}=\frac{1}{18487500\times \pi }\times 180^{o}=0.0000031^{o}

2)

The angular separation in arc- seconds is given by

\theta ''=\theta ^{o}\times 3600\\\\\theta'' = 0.0000031\times 3600=0.011156"

The major industrial nations of the world, like the United States and China, are also the world's largest
Vinvika [58]

Answer:

This problem should be worked on by the most developed countries as they have the biggest capacity, and after they get on the right way to help the developing countries and show them the way as to how to do it as well.

Explanation:

The carbon emissions that humanity is releasing into the atmosphere can not be attributed to only a few countries, but to most of the countries in the world. All countries that have some kind of industry contribute to the problem, though some countries much more than others.

In order for carbon emissions to decrease there should be a global collaboration. The most developed countries because they have the most finances and resources should lead the way and come up with solutions, and once they do this to help the developing countries with it so that they can also stop the carbon emissions.

Many countries are already on the right path, namely Germany, the Netherlands, France, the Scandinavian countries. The two biggest economies though, the US and China don't even want to hear about this because of their race for economic dominance, so it seems that reasoning the governments of these two countries will be the most important step for global turnaround.
