To solve a problem using the equation for Kepler’s third law, Enrico must convert the average distance of Mars from the Sun from

vovikov84 [41]

Answer:Enrico must multiply the distance of mars from sun (meters) with the $6.6844\times 10^{-12}$ to convert the distance in astronomical units.

Explanation:

1 astronomical unit = $1.496\times 10^{11} m$

$1m=\frac{1}{1.496\times 10^{11} } AU=6.6844\times 10^{-12} AU$

Let the distance between the sun and Mars be Y( meters)

Distance in AU= $Y\times 6.6844\times 10^{-12} AU$

Enrico must multiply the distance of mars from sun (meters) with the $6.6844\times 10^{-12}$ to convert the distance in astronomical units.

When layers are compacted and heated over time, deposits are turned into coal. Whereas Oil is a liquid fossil fuel that is formed from the remains of marine microorganisms deposited on the sea floor and gas like oil, it is formed from the remains of marine microorganisms.
So the difference could be how they are formed
