1,000 kg car is travelling at 6.5 m/s to the North. A 3,500 kg truck is also travelling North at the same velocity. What is the total momentum of the two vehicles? Please answer ASAP

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

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.
