In a dragster race cars are traveling so fast that they must deploy a parachute to come to a stop. How is this scenario different from our prior questions?

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

that would be because of both gravity and friction. so     c

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.
