Aleksandr [31]

Answer:

The gravitational potential will change more on  earth.

Explanation:

The gravity on the moon is only 17% of that of earth's because the earth has way more mass. Since the gravitational potential depends on the mass of the human and the height of the ladder, and both things will remain equal, no matter where they are, so we could assume that the gravitational potential energy will change more on earth.

Misha Larkins [42]

Answer:

When the magma, a molten rock flows as lava at the planet's surface, the surface gets cooled after a long, this whole process cause formation of some kinds of minerals on that surface.

Explanation:

Magma and Lava both are types of molten rock. The underground molten rock is called magma while the exploded molten rock on surface is known as lava. When these rocks cools down they get solidified and form crystal rock structure. Cooled magma is called plutonic igneous rock and cooled lava is called volcanic igneous rock. These rock crystals are of different sizes and consist several minerals such as Silicon(Si), Sodium (Na), Potassium (K), Aluminium (Al), Iron(Fe), Magnesium(Mg), Calcium(Ca). Some rocks that forms minerals consist high amount of iron. The amount of minerals and elements in every rock can very depending on shape and size.

If a white dwarf or neutron star were to gain mass, it would _____.
Vanyuwa [196]
<span>
c</span><span>A. grow larger
</span><span>
The mass of the star actually determines the stage of the star after supernova. If the mass of the star is small, then it would become a very small and dwarf, cold and dead body in space. The mass of the star has to be less than that of the sun. If the mass of the star is greater than sun, then it would become a black hole. The mass of the star has to be more than 1.4 times the mass of the sun to become a black hole.

Nebula is the cloud of interstellar dust and gas that forms a star. It is collborately shaped during colliding and collapsing of the interstellar mediums this is influenced by the gravitational attraction of the atoms and particles in the entites. Hence, there are three types of nebular namely, are classical nebula, diffuse nebula, planetary nebular and supernova remnants.
