Question

mean distance of the earth
from the sun is 149
e earth is 1.0 year. The average mean distance of mars from the sun is 1427000000km. using keplers third law culculate the period of mars​

Answer 1

Answer:

 Kepler's law of periods, expressed as a ratio, is

(aEaM)3=(TETM)2⇒(1.52)3=(1yTM)2

where we have substituted the mean-distance (from Sun) ratio for the semi-major axis ratio. 

This yields TM=1.87y.

Answer 2

Answer:

Kepler's third law can then be used to calculate Mars' average distance from the Sun. Mars' orbital period (1.88 Earth years) squared, or P2, is 1.882 = 3.53, and according to the equation for Kepler's third law, this equals the cube of its semimajor axis, or a3.

Explanation:

If the size of the orbit (a) is expressed in astronomical units (1 AU equals the average distance between the Earth and Sun) and the period (P) is measured in years, then Kepler's Third Law says P2 = a3.
