(a) System models are used to assist in understanding an actual system and we usually develop and use models that are exact representations of the actual system.
1-True
2-False
(b) What statement best describes how a static system differs from a dynamic system?
1. A static system's characteristics are fixed regardless of the state of any external factors in its environment.
2. A static system always exhibits a linear relationship between its inputs and its outputs.
3. Static systems are the most common system type used to model complex systems.
