Answer the following statement(s) true (T) or false (F)

1. We can consider a set of all chlorine atoms in a block of salt (sodium chloride) to be a “system.” 2. We can consider that set to be an “extended object.” 3. Consider a three-particle system. The center of mass of this system must lie on the plane that contains all three particles. T or F? Be prepared to explain why or why not. 4. In the situation discussed in problem C4T.10, which would be the easiest reasonably valid frame to use? 5.
