Economic resources of the Rocky Mountains are varied and abundant. Minerals found in the Rocky Mountains include significant deposits of copper, gold, lead, molybdenum, silver, tungsten, and zinc. The Wyoming Basin and several smaller areas contain significant reserves of coal, natural gas, oil shale, and petroleum.

Suppose that two stars in a binary star system are separated by a distance of 80 million kilometers and are located at a distanc

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

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

The angular separation in arc- seconds is given by

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