{"Image DocumentName": "9.9 Efficiency", "Image ImageDescription": "The efficiency of a machine is the ratio of useful energy output to total energy input\u2014the percentage of the work input that is converted to work output. To convert efficiency to percent, you multiply by 100%. An ideal machine would have 100% efficiency. No real machine can be 100% efficient. Wasted energy is dissipated as heat.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
