a. The drawing shows Samir riding his mountain bike. Write down the places where there should be a lot of friction. Explain why? b. Note down the places where there should be low friction. C. How can Samir make sure the friction in these places is as low as possible?​

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

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.
