What is the average density of neptune if the acceleration due to gravity on its surface is 11 m/s2 and its radius is 2.48 107 m

Explanation:

Acceleration due to gravity is given by

     G =6.67 x 10⁻¹¹ Nm²/kg²

      M = Mass

      R = Radius

Substituting

Mass of Neptune is 1.01 x 10²⁶ kg

Now we have equation for volume,

We have

          Mass = Volume x Density

           1.01 x 10²⁶ = 6.39 x 10²² x Density

           Density = 1581 kg/m³  

Density of Neptune is 1581 kg/m³  

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.
