A bus has velocity 20m/s towarda east and another bus has velocity 15m/s in west direction . If they start to move from a point simultaneously , what distances they cover in 2 minute ? What will be their separation ? ​

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

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.
