NASA pointed the Hubble Space Telescope at a very dark section of sky to see what might be found. The telescope revealed about 10,000 distant and never-before-seen galaxies. NASA would have to make observations of more than 10,000,000

other sections to study the rest of the sky. If every section of sky also looked out on 10,000 galaxies, about how many

galaxies would exist in the known universe?

100,000,000,000

Explanation:

Given that :

1 hubble space telescope pointed at 1 section of the sky reveals 10,000 distinct galaxies ;

Number of sections from which observation is to be made = 10,000,000

Number of distinct galaxy per section = 10,000

Number of galaxies that would exist in the known universe :

Total number of galaxies in the known universe :

Number of galaxies per section * number of sections

10,000 * 10,000,000

= 100,000,000,000s

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
