Calculate the distance of the galaxies with the following redshifts (assume a Hubble Constant of H0 = 72 km/s/Mpc): [10 pts.]
Redshift Distance
(z) (Mpc)
0.02
0.1
0.2
0.5

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

does anyone know or what?

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
