Compared to the earth , planet X has twice the mass and twice the radius. This means that compared to the amount of energy required to move an object from the earth s surface to infinity, the amount of energy required to move that same object from planet X s surface to infinity is:.

Same

Explanation:

Compared to the earth , planet X has twice the mass and twice the radius. This means that compared to the amount of energy required to move an object from the earth's surface to infinity, the amount of energy required to move that same object from planet X's surface to infinity is the same with that of the amount of energy required to move objects from earth

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
