Asolid cylinder with an unknown radius starts from rest at the top of a 12.0m long ramp inclined 20.3∘ above the horizontal. calculate the cylinder's final velocity when it reaches the bottom of the ramp.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

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.
