Planet Z-34 has a mass equal to one-third that of Earth and a radius equal to one-third that of Earth. With g representing, as usual, the acceleration due to gravity on the surface of Earth, the acceleration due to gravity on the surface of Z-34 is

The acceleration due to gravity on the surface of Z-34 is equal to   .

Explanation:

Here we know that acceleration due to gravity on a planet of mass M and radius R is given by  

Given that mass of earth is M and radius is R .

  Mass of Z-34 = ,

  Radius of Z-34 =

 G = gravitational constant .

    = acceleration due to gravity on Z-34 ,

answer: strength i guess

explanation:

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
