How much ice at a temperature of -16.5 ∘c must be dropped into the water so that the final temperature of the system will be 26.0 ∘c ? take the specific heat of liquid water to be 4190 j/kg⋅k, the specific heat of ice to be 2100 j/kg⋅k, and the heat of fusion for water to be 3.34×105 j/kg . view available hint(s)

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.
