1. The purpose of studying the various velocities and the distances of galaxies in
these studies was:
A. To prove that galaxies were moving
B. To determine the Hubble constant
(H.) which helps determine the age
of the universe
C. To determine the size of a galaxy
which helps determine the Hubble
constant (H.)
D. To determine the age of the universe
which helps determine the Hubble
constant (H)

58750.08068 is the answer i think

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
