Final answer:
Option B, 'Attach the cup to the windmill and let it be lifted,' is the correct answer to use a cup when the windmill lifts it up, as it relates to a physics principle being demonstrated in the scenario.
Step-by-step explanation:
To answer your question about how you would use a cup if it starts on the table and then the windmill lifts the cup up, you would choose option B. Attach the cup to the windmill and let it be lifted. This is because the question seems to be describing a scenario where the cup is being moved by an outside force, similar to an experiment demonstrating principles of physics, such as energy transfer or rotational motion.
In various physics experiments, motion and forces are explored using different methods. For example, by attaching an object to a string and swinging it around, you can investigate circular motion. Similarly, you can roll a marble through a pipe to understand motion and gravitational forces. In an experiment with a wind power concept, the motion of air through the rotor of a wind turbine is analyzed. Attaching a pen to a record player can help you explore uniform circular motion by capturing the pen's path on paper.
