the orbital period, $p$, of a planet and the planets distance from the sun, $a$, in astronomical units is related by the formula $p = a^{\frac{3}{2}}$. if saturns orbital period is 29.5 years, what is its distance from the sun?\n9.5 au\n19.7 au\n44.3 au\n160.2 au
Answer
Explanation:
Step1: Substitute given values
Given $P = 29.5$ and $P=a^{\frac{3}{2}}$, so $29.5=a^{\frac{3}{2}}$.
Step2: Solve for $a$
Raise both sides to the $\frac{2}{3}$ power: $a = 29.5^{\frac{2}{3}}$. Using a calculator, $a=9.5$.
Answer:
A. 9.5 AU
