Out in the woods filming a documentary about timber rattlesnakes, your video camera runs out of batteries. The camera draws 0.25 A of current, and has an overall resistance of 72 ohms. What voltage supply does this camera need - well your last 6 pack of 9V batteries do the job?

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.
