12. an electric dipole is held at rest so its dipole moment of 0.049 c-m makes an angle of 3 degrees with a uniform electric field of 150 n/c. if we release the dipole so it is free to turn with its moment of inertia of i = 1.5 kg-m what is the dipole's approximate angular frequency of oscillation, ω, in radians/second?

float.

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.
