Suppose that two stars in a binary star system are separated by a distance of 80 million kilometers and are located at a distanc
jonny [76]

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"

non working population is a burden on working population explain why might you agree and disagree with the statement
Nikitich [7]

Answer:

Indeed, non working population is an unfair burden on working population. This is so because the unemployed population, in general, tends to receive assistance from the government, which in turn is financed through taxes that are collected from those who do work. Thus, there is a kind of arbitrary redistribution of income that damages workers in favor of those who do not work.
