Asatellite can move at 17,000 miles per hour. how many hours will it take to reach a star that is three light years away? recall that 1 light year = 9.5 ∙ 1012 kilometers and 1 kilometer = 0.62 miles. show your work.

1 light year = 9.5 * 10^12 kilometers

1 light year = 5.9 * 10^12 miles

3 light years:

3 * 5.89 * 10^12 miles =

1.767 * 10^12 miles =

1.767 * 10^13 miles

How long does it take to get there?

(1.767 * 10^13) / (17000) =

(1.767 * 10^13) / (1.7 * 10^4) =

1.03941176471 * 10^9 =

1039411764.71 ≈ 1,040,000,000

It will take about 1,040,000,000 hours to get to a star that is 3 light years away.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
