40 points, due tonight, please explain, I keep getting different answers 2. A ball of mass 0.2 kg is placed in a small cup on a vertical spring with a spring constant 400 N/m.
The spring is compressed 0.1 m and released. Ignoring air resistance, the maximum height of the
ball above its starting point is most nearly
(A) 20 m (B) 10 m (C) 2 m (D) 1 m

explanation:

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.
