select all the correct answers. which two statements are true about a system? a system is a group of objects analyzed as one unit. energy that moves across system boundaries is conserved. there’s only one way to define the boundaries of a system. all systems are made by humans.

Answer

Brief Explanations:

  • A system is indeed a group of objects analyzed as one unit. This is a fundamental definition.
  • Energy is conserved in an isolated - system when it moves across boundaries in an ideal situation. But the statement doesn't specify the type of system (isolated or not). However, in general, energy conservation is a key principle related to systems.
  • There are multiple ways to define system boundaries depending on the context and the analysis being done.
  • Not all systems are made by humans; natural systems exist, such as ecosystems.

Answer:

A. A system is a group of objects analyzed as one unit. B. Energy that moves across system boundaries is conserved.
