Sampling can be done randomly or in a systematic way. The goal of sampling is using the part to represent the whole.
Answer:
Polluting energy system are given below.
Explanation:
- Polluting Energy Systems like the Industrial systems that are stationary power systems along with the mobile pollutant system like vehicles and examples of heating systems like those of the air furnaces, hot water boilers, and electric heat pump.
- Example of Propulsion System is spacecraft and aircraft from a launch vehicle. Turbines are also characterized by having a propulsion system. Cooling Systems like the coolants in vehicles, computers and air conditioners and refrigerators, etc.
- All these follow the traditional energy system models as they stay locked from outside and derive the system by the energy created due to electric induction.
