Final answer:
It is true that you should replace microdermabrasion tubes when they show signs of wear, such as becoming brittle and inflexible. For additional information, wave-particle duality only applies to microscopic particles and dropping a bar magnet through a copper tube does induce an electric current.
Step-by-step explanation:
The statement “Replace microdermabrasion tubes when they become brittle, inflexible, and less translucent” is true. Microdermabrasion tubes are an essential component in a microdermabrasion machine, which is a device used for skin treatments. Over time, these tubes can degrade due to use and exposure to different substances, which can affect their performance and safety. Therefore, it is important to replace them when signs of wear, such as brittleness or a lack of flexibility, are observed to maintain the effectiveness and hygiene of the treatment provided.
As for the physics-related true or false questions for clarification:
- The statement “Wave-particle duality exists for objects on the macroscopic scale” is false. Wave-particle duality is a concept in quantum mechanics that is observable for microscopic particles, like electrons and photons, but not for macroscopic objects.
- Regarding the second statement, “If you drop a bar magnet through a copper tube, it induces an electric current in the tube,” the correct answer is true. This phenomenon is explained by Faraday's law of electromagnetic induction. When the magnet falls through the copper tube, the changing magnetic field as the magnet moves induces an electric current in the tube.
