According to the law of conservation of energy, which changes would increase the total energy of a system?
A. An addition of 400 J of GPE and a loss of 250 J of thermal energy
B. An addition of 100 J of thermal energy and a loss of 450 J of
kinetic energy
C. An addition of 200 J of kinetic energy and a loss of 250 J of
thermal energy
D. An addition of 300 J of thermal energy and a loss of 450 J of
kinetic energy

C. in addition of 200 J of thermal energy in a loss of 350 J of kinetic energy

i took the test

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

where is the circuit diagram ?
