A 1500kg train travels east at 25m/s and collides with 800 small car which was initially at rest .The train and small car stick togather and move off in one direction .Prove by calculating whether the collision is elastic ir inelastic?

show the wavelengths of a wave. show the crests of a wave.

neither accurate nor precise.

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.
