<span>The English Channel separates the UK from the continent of Europe, in particular France. Many have tried to swim it as a challenge. It is a body of water. There are many boats and fairies which use it to get people from one place to nother. Tourists often travel on it when they want to go from the UK to Europe and vice versa.</span>
I believe that your answer is #4, it seems to be the only logical one. :)
Answer: 100Mpc
Explanation:
Hubble deduced that the farther the galaxy is, the more redshifted it is in its spectrum, and noted that all galaxies are "moving away from each other with a speed that increases with distance", and enunciated the now called Hubble–Lemaître Law.
This is mathematically expressed as:
(1)
Where:
is the approximate recession velocity of the galaxy
is the Hubble constant
is the distance
Now, we have two galaxies A and B ande we know the following:
Galaxy A has a velocity twice that of galaxy B
(2)
Galaxy A is 200 Mpc away
(3)
According to Hubble Law:
(4)
(5)
Substituting (2) in (5):
(6)
(7)
(8)
If 
(9)
(10)
Substituting (8) in (11):
(11)
Finally:
Answer:
When its molecules lose energy, water becomes solid, it becomes ice. At falling temperatures, the density of water is altered. Water is formed by atoms and molecules. Falling temperatures lead to changes in that compound, in its volume. While density increases because of lower temperatures, water´s atoms and molecules get more tightly packed together. Water freezes from the top down.
Explanation:
magma, rises through cracks and erupts to form volcanoes. The answer id D. Hotspot volcanism would thus be unique because itdoes not occur at the boundaries of Earth's tectonic plates, where other volcanism occurs.
