Answer:
A. The astenosphere is denser than the lithosphere
Explanation:
The theory of isostasy is a theory that suggest that the layers of Earth are arranged in accordance to their density. It is a theory that usually refers to the mantle and crust. The mantle (astenosphere) is denser than the crust (lithosphere), so the crust floats on top of it, depending on its density, with he continental crust being higher, while the oceanic crust being lower. The two forces that are responsible for this are the gravity and buoyancy.
<u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u><u> </u>Both things will help slow the rate of climate change by lowering air pollution, rejuvenating the soil, giving animals shelter, and less energy waste.
Sorry if it isn't long enough but you can stretch out what I said!
Hola, espero que estés teniendo un gran año.
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}](https://tex.z-dn.net/?f=%5Ctheta%20_%7Brad%7D%3D%5Cfrac%7BS%7D%7BD%7D)
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](https://tex.z-dn.net/?f=%5Ctheta%20_%7Brad%7D%3D%5Cfrac%7B80%5Ctimes%2010%5E%7B6%7D%7D%7B150%5Ctimes%209.46%5Ctimes%2010%5E%7B12%7D%7D%5C%5C%5C%5C%5Ctherefore%20%5Ctheta%20_%7Brad%7D%3D%5Cfrac%7B1%7D%7B18487500%7Dradians)
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}](https://tex.z-dn.net/?f=%5Ctherefore%20%5Ctheta%20_%7Bdegrees%7D%3D%5Cfrac%7B1%7D%7B18487500%5Ctimes%20%5Cpi%20%7D%5Ctimes%20180%5E%7Bo%7D%3D0.0000031%5E%7Bo%7D)
2)
The angular separation in arc- seconds is given by
![\theta ''=\theta ^{o}\times 3600\\\\\theta'' = 0.0000031\times 3600=0.011156"](https://tex.z-dn.net/?f=%5Ctheta%20%27%27%3D%5Ctheta%20%5E%7Bo%7D%5Ctimes%203600%5C%5C%5C%5C%5Ctheta%27%27%20%3D%200.0000031%5Ctimes%203600%3D0.011156%22)
