How does the sahara desert act like a barrier between North Africa and sub-saharan Africa.

GuDViN [60]

Answer:

It is difficult to cross.

Explanation:

The Sahara desert is a vast region about the size of the continental United States that is extremely dry and barren. The lack of water resources in the desert make the land unsuitable for agriculture and human population.

As a result, the Sahara acts as a giant natural wall both economically, culturally, and socially since relations between states to the north and south of the desert are difficult.

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

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