Which of these sequences lists units of astronomical measurement from smallest to largest?

A. light-year --> AU --> kilometer --> mile
B. light-year --> AU --> mile --> kilometer
C. kilometer --> mile --> AU --> light-year
D. mile --> kilometer --> AU --> light-year

C. kilometer --> mile --> AU --> light-year

Explanation:

Option C is the right because kilometer is the smallest unit in the given options. Mile is a greater unit than a kilometer and the Astronomical unit is greater than miles. The light-year is the largest one.

1 km = 0,621 miles

1 mile = 1,07578e-8 Astronomical unit (AU)

1 AU = 1,58125e-5 light year

answer: your mm

explanation:

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
