Answer:

D) Europa

A) Ganymede

C) Callisto

B) Io

Explanation:

  • A tidal heating is also known as the tidal fluxing and occurs by the tidal friction that is a product of the orbital energy of the moon either on the surface or either under the surface. Hence the deformation of the body is due to the tidal bulge.  
  • <u>A product of the gravitational energy and this is known to be responsive to the formation of the geologic activity. Lo moon and Europa and the Ganymede have the same mechanism that provides with the energy to melt the ice layer and thus all the body's radius, density, and rheological parameters are needs for the formation of this system.</u>

1. The First Quarter Moon always occurs
Artemon [7]

Answer:

1.- b. when the Moon is at right angles to the direction of the Sun.

2.-b. when the Moon is directly opposite the position of the Sun.

3.-b. when the Moon is closer to the Sun than the Earth is.

Explanation:

  • The First Quarter Moon is when we can see exactly half of the Moon's surface illuminated. If it is the left or right half, it depends on where you are on Earth. If we observe the diagram I added we can see than <em>the moon is at right angles to the direction of the Sun</em> when it's in this phase.
  • Full Moon happens when<em> the Moon is on the opposite side of the Earth from the Sun</em>, this makes the bright side of the Moon face the Earth. This is also observable in the diagram.
  • The New Moon always occurs when <em>the Moon is between the Earth and the Sun, therefore it's closer to the Sun than the Earth</em>, the bright side of the Moon is facing away from the Earth. You can check this in the diagram as well.

I hope you find this information useful and interesting! Good luck!

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"

What is essential for a confederation?
user100 [1]

Answer:

smaller political units maintaining their sovereignty

Explanation:

Confederation is the name given to a country that is a federation, but the states that make up that country maintain their sovereignty, separate from the power of the federal government. In this case, to maintain a confederation it is essential that the smaller political units, the states, maintain their sovereignty. This is different from a federation, because in a federation, states lose sovereignty, transferring it to the federal government.
