Sergeu [11.5K]

Answer:

planet that is farthest away is planet X

kepler's third law

Explanation:

For this exercise we can use Kepler's third law which is an application of Newton's second law to the case of the orbits of the planets

          T² = (\frac{4\pi ^2}{ G M_s} a³ = K_s a³

           

Let's apply this equation to our case

          a = \sqrt[3]{ \frac{T^2}{K_s} }

for this particular exercise it is not necessary to reduce the period to seconds

Plant W

             10² = K_s  a_{w}^3

             a_w = \sqrt[3]{ \frac{100}{ K_s} }

             a_w = \frac{1}{ \sqrt[3]{K_s} }  4.64

Planet X

             a_x = \sqrt[3]{ \frac{640^3}{K_s} }

             a_x = \frac{1}{ \sqrt[3]{K_s} } 74.3

Planet Y

              a_y = \sqrt[3]{ \frac{80^2}{K_s}  }

              a_y = \frac{1}{ \sqrt[3]{K_s} } 18.6

Planet z

              a_z = \sqrt[3]{ \frac{270^2}{K_s} }

              a_z = \frac{1}{ \sqrt[3]{K_s} } 41.8

From the previous results we see that planet that is farthest away is planet X

where we have used kepler's third law
