The scale of a spring balance reading from 0 to 170 \rm{N} has a length of 11.0 \rm{cm}. A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.20 \rm{Hz}. Ignoring the mass of the spring, what is the mass m of the fish? Please walk me through the process as well.

In this problem, you will calculate the location of the center of mass for the Earth-Moon system, and then you will calculate the center of mass of the Earth-Moon-Sun system. The mass of the Moon is 7.35×1022 , the mass of the Earth is 6.00×1024 , and the mass of the sun is 2.00×1030 . The...
