Aworker is holding a filled gas cylinder still. which two sentences are true about the energy of the filled gas cylinder? a-it has no energy because it’s being held still. b-it has gravitational potential energy because of its height. c-its atoms and molecules have thermal energy. d-it has motion energy because it will fall if let go. f-its kinetic energy is being converted to potential energy.

it becomes positively charged by charging it

c) up is the direction the magnetic force is acting on the charge.

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.
