.
Je réponds directement
Schématise la situation et représente les forces de
gravitation s'exerçant entre la Terre et ce satellite en
prenant comme échelle 1 cm pour 100 N.

the answer would be c

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

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.
