The flashlight shown has no batteries. It operates by squeezing and letting go of the handle. Inside the body of the flashlight are gears. What energy transfers take place within the flashlight to produce light?
mechanical energy → electrical energy → light energy
mechanical energy → chemical energy → light energy
chemical energy → mechanical energy → light energy
chemical energy → electrical energy → light energy
