Final answer:
The message indicating an answer is complete and correct typically means full credit has been earned, which is true. Ensuring all parts of the question are addressed and the answer is reasonable within the problem's context is critical.
Step-by-step explanation:
The message “Answer is complete and correct” in the “Check my work” feature typically indicates that full credit has been earned for that question, so the answer would be True. However, always ensure you have addressed all parts of the question and that your answer is reasonable and makes sense within the context of the material. For example, in a math problem where you are calculating the volume of an object, if your answer is unexpectedly in cubic kilometers, you may need to recheck your conversions or calculations unless the context of the problem suggests that such a large measure is appropriate.
Similarly, in a physics context, when asked about the efficiency of a simple machine, the statement that 'The efficiency of a simple machine is always less than 100 percent because some small fraction of the input work is always converted to heat energy due to friction' is True. No machine can be 100% efficient due to energy losses, primarily through heat due to friction.
