Pick a launch speed and angle and compare the time required for the projectile to rise to the peak of its trajectory to the time for the projectile to fall from the peak of its trajectory.
Repeat for other launch angles if necessary. Describe your findings

the diagram which shows forces as either balanced = same speed or unbalanced = accelerarting

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.
