Aboy and a girl are balanced on a seesaw. the boy has mass of 50 kilograms and the girl has mass of 31 kilograms. if the boy sits 2.1 meters from the pivot point (fulcrum) on one side of the seesaw, how far from the pivot point on the other side must the girl sit in order to keep the seesaw balanced?

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.
