Planet x has the half the size of earth and a density three times that of the earth. determine the acceleration due to gravity on planetx select one: 9/2 2g/3 39/2 2g 3

Explanation:

As we know that the acceleration due to gravity is given as

now we know that mass is the product of density and volume

so we will have

Now we have

now size of new planet is half that of size of Earth and the density is 3 times the density of Earth

so we have

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
