Agalaxy is sitting at a redshift of 7. a) what color will the galaxy appear to be at this redshift? b) what temperature does the universe have at this redshift?

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

i think it would be 5

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
