Light with a frequency of 6 x 10^14 Hz is shown upon a metal surface with a work function of 1.3 eV. As a result of the light striking this surface, electrons are ejected. The threshold frequency for this metal is Hz

The energy of the light striking the metal is eV

The kinetic energy of the electrons that are ejected from the surface is eV

i would say

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.

answer is slate

hope this
