For any object orbiting the Sun, Kepler's Law may be written T2 = kr3. If T is measured in years and r in unit

T = 1.==============-1.8 years. Since the number of significant digits in the least accurate measurement is two, any number with more significant figures is incorrect. (ie.......
For any object orbiting the Sun, Kepler's Law may be written T2 = kr3. If T is measured in years and r in units of the Earth's distance from the Sun, then k = 1. What, therefore, is the time (in years) for Mars to orbit the Sun if its mean radius from the Sun is 1.5 times the Earth's distance from the Sun?

-
k = T²/ r^3
Since k = 1

T² = r^3 where T is in years and r is in units of earth distance to the sun

Given r = 1.5 units
T² = 1.5 ^3

T = 1.84 years

1.8 years. Since the number of significant digits in the least accurate measurement is two, any number with more significant figures is incorrect. (ie. 1.837117307 years)

-
T^2 = k * r^3
For the earth, T = 1 year, k = 1, and r = radius of earth
For mars, radius = 1.5 * r

T^2 = 1 * 1.5^3 = 3.375
T = √3.375 ≈ 1.837 years

-
T^2 = (1.5)^3

1.5*1.5*1.5 = 2.25*1.5 = 3.375

T = sqrt(3.375)

plug that into a calculator for the answer

-
T² = Kr³

Now for mars it should be,
T = √(Kr³)
= √(1*r²*r)
= r√r
Now put the radius of earth to get the orbit time for mars.
