Abaseball sitting on the roof of the stadium has 60 j of potential energy. a pigeon lands on the baseball and knocks it off. how fast will the baseball be traveling the instant before it strikes the ground? assume the baseball weighs 150 grams, and that all of the potential energy is converted into kinetic energy.

d. air pressure decreases as altitude increases.

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.
