Final answer:
The statement about SortingMachine is off-topic, but the reference question's answer is true—no simple machine is 100% efficient due to energy loss from friction as heat.
Step-by-step explanation:
The statement concerning SortingMachine is unrelated to the question provided for reference. However, the reference question can be answered. The efficiency of a simple machine is always less than 100 percent. This is true because in the physical world, some amount of the input work is inevitably converted to heat due to friction. In any machine, energy transformations are not perfectly efficient, and the concept of friction plays a significant role in this inefficiency. This loss of energy as heat means that the output work is always less than the input work, preventing 100% efficiency.
