From their redshifts, calculate the speed at which each of the galaxies is moving away from us. give your answers in km/s.
wel
The math suggests that for every parsec the rate of moving away is 71 km/s, so when two galaxies are separated by two parsecs we come to 142 km/s speed of moving away from each other. If we take the first light ever (from what is known so far) the cosmic microwave radiation, is 46 billion light-years away from us at all directions, which comes at 4,200 megaparsecs, which comes at 13.7 billion light-years, so it will come to 29,820,000 km/s. It all depends from the distance between the galaxies which is calculated by their type of colour and movement in comparison to other galaxies.

How would you distinguish between rhyolite porphyry, andesite porphyry, and basalt porphyry
Mrac [35]

<u>Basalt</u>

<em>     </em><em>Formation</em> -basalt is (mineral) a hard igneous rock of varied mineral   content formed when lava reaches the Earth's surface near an active volcano

<em>     </em><em>Texture</em>-  is fine grained so the individual minerals are not visible

<em>     </em><em>Colour</em>- basalt being dark

<u>Rhyolite</u>

<em>       Formation</em> -Rhyolite is a very fine-grained to glassy extrusive igneous rock. Formed in continental plates have  volcanic eruptions.

<em>     Texture</em>- very small than grains and are difficult to observe without using a hand lens.

<em>     </em><em>Colour</em>- light in colour whether  pink or grey  

<u>Andesite</u>  

<em>     </em><u><em> </em></u><em>Formation</em>- Andesite is a fine-grained igneous rock that forms when the magma is rises up onto the surface and  crystallized quickly

<em>     </em><em>Texture</em>- higher than basalt and lower than rhyolite  

<em>     </em><em>Colour</em><em> -</em>- color is pale due to silica content
