Block X and Block Y are tied together by a rope. The system containing Block X and Block Y is dropped above Earth's surface in the orientation shown in the figure. Block Y has a larger mass than Block X. Which of the following claims is correct regarding the momentum of the system containing only Block X and the system that contains Block X and Block Y? A The system containing Block X is an open system, and the system of both blocks is an open system B The system containing Block X is an open system, and the system of both blocks is a closed system. с The system containing Block X is a closed system, and the system of both blocks is an open system. The system containing Block X is a closed system, and the system of both blocks is a closed system.​

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature.the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system.the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system.the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.
