think back to the last time you rode a roller coaster or amusement ride that made you feel weightless. using your knowledge of forces, explain why this happens.

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.

the answer is the last option

explanation:

because in order to know what the molecule is you need to know how many atoms of each element are in the molecule.
