In a canyon between two mountains, a spherical boulder with a radius of 1.2 m is just set in motion by a force of 1600 N. The force is applied at an angle of 38.1 ◦ measured with respect to the radius of the boulder?

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

snell's law

refractve index = sin incidence / sin refraction

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.
