The equation T squared = A cubed shows the relationship between a planet’s orbital period, T, and the planets mean distance from the sun, A, in astronomical units, AU. If planet Y is twice the mean distance from the sun as planet X, by what factor is the orbital period increased?

orbital period increased by a factor of 2.83 unit

Explanation:

Given.

planet’s orbital period, T, and the planets mean distance from the sun, A, in astronomical units, AU

T²= A³

If A is increased by a factor of 2 , .

Then T will be increase with the factor of √2³ = 2.83
