20 POINTS Kathy and Quinn decide to go for a two day hike. They leave their base camp and hike 38.0 km at 35 degrees south of east. On the second day they walk 46.0 km in a direction of 65 degrees north of east and find a forest ranger´s tower. Determine the magnitude and direction of their resultant displacement between the base camp and the ranger´s tower.

Research the neutrino using the internet and report your findings. in a nuclear decay, the nucleus of an atom splits apart. larger particles can be detected and their masses and velocities can be recorded. explain how the existence and properties of the neutrino could be predicted using the conservation laws.
