Answer:
<em>The comoving distance and the proper distance scale</em>
<em></em>
Explanation:
The comoving distance scale removes the effects of the expansion of the universe, which leaves us with a distance that does not change in time due to the expansion of space (since space is constantly expanding). The comoving distance and proper distance are defined to be equal at the present time; therefore, the ratio of proper distance to comoving distance now is 1. The scale factor is sometimes not equal to 1. The distance between masses in the universe may change due to other, local factors like the motion of a galaxy within a cluster. Finally, we note that the expansion of the Universe results in the proper distance changing, but the comoving distance is unchanged by an expanding universe.
Answer:
3 Objects that carry instruments into the stratosphere to measure atmospheric conditions
Explanation:
Weather balloons are objects that carries instruments into the stratosphere to measure atmospheric conditions.
They are very important weather measuring device that helps meteorologists in their fore casts.
These balloons are specially designed for high altitudes. They carry very sensitive devices that are very useful in collecting information about temperature, precipitation, pressure e.t.c
Answer:
Velocity
Explanation:
Velocity is a speed with a direction.
I say the answer is eating chicken. Eating chicken provides many nutrients such as, protein, diabetes, and somminilla.
1.plants,most algae and cyanobacteria
2.during photosynthesis cells use carbon dioxide and energy from the sun to make sugar molecules and oxygen
3.carbon dioxide+water---Glucose+oxygen
4.chloryphil
5.it absorbs blue and red good and absorbs green poorly
6 In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle
