A ball is thrown horizontally with a speed of 21.8 m/s from a roof that is 13.0 meters high. How far away from the building (meters) does the ball hit the ground?

what type of charge does it have? negative

answerscientific theory;

prndulum needs thread, weight clock to time swings

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.
