Which of the following statements are true regarding a non-isolated system and its energy? a. A mathematical statement of conservation of system energy for a non-isolated system is as follows b.If the total energy of a system changes, then the system was not isolated. C. The total energy of a system will change if work is done on or by the system. d.The total energy of a system can change if matter, electromagnetic radiation, mechanical waves or electric charge is transferred into or out of the system. e.The familiar work-kinetic energy theorem Wext-AK is a special case of conservation of energy for an isolated system consisting of many particles. f.
