Which statement describes one way that nuclear fission differs from nuclear fusion?

A. Nuclear fission is used to produce electrical power.
B. Nuclear fission requires very high temperatures.
C. Nuclear fission occurs naturally only in the Sun and other stars.
D. Nuclear fission is too hard to control for use in practical
applications.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

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.
