Max (15 kg) and maya (12 kg) are ice-skating on a frozen pond. at one moment, when max is skating away from the shore at 8.2 m/s and maya is skating towards the shore at 4.6 m/s, they collide and bounce off each other without falling. if maya rebounds at 3.4 m/s, what is max’s velocity after their collision?

I'm thinking it's 2 you are asked to explain the earth's magnetic field. which is the best reply? 1. the earth's magnetic south is similar to the north pole of a magnet. 2. the earth's core has a strong magnetic charge similar to the south pole of a magnet. 3. the earth's geomagnetic south is similar to the south pole of a magnet. 4. the earth's magnetic charge is not centered at either pole; it varies based on location.
