The total energy of a system remains unchanged during a cycle. a) - True b) - False

Answer: True

Explanation: It is correct that during a cycle the energy of the system remains unchanged. Total energy consist of the initial energy and the final energy in a system and both remain equal in a system whether they are in cycle or not ans also according to the law of conservation of energy, total energy cannot be destroyed or created. Thus the while a cycle goes on energy will remain the same.
