What is instantaneous speed nd velocity​

Instantaneous speed is the exact speed that an object in motion has at a given instant in time.

Instantaneous velocity is the exact velocity that an object in motion has at a given instant in time.

Explanation:

Instantaneous velocity tells how fast an object is moving anywhere along its path.

Instantaneous speed at an instant is equal to the magnitude of the instantaneous velocity at that instant.

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.
