Final answer:
This fragmented question addresses different practices for health and safety concerning electronics and protective wear. Polarized sunglasses work best when worn properly, and minimizing electronic device usage during class can lead to better academic performance. Working 'one-handed' with electric circuits is a safety protocol to prevent electric shock.
Step-by-step explanation:
The original question appears to be fragmented and unclear, but it touches upon the health and safety practices related to electronics and protective wear, such as sunglasses and the importance of reducing distractions from electronic devices in a classroom setting. Polarized sunglasses do not work well when your head is tipped sideways because the orientation of the polarized filter is crucial for blocking horizontal light reflections effectively. Furthermore, reducing multi-tasking with electronic devices during class activities has been shown to improve student grades, as it helps to maintain focus and attention. In terms of health safety, when working with high-power electric circuits, working 'one-handed' is suggested to prevent the possibility of creating a circuit through your body, which could result in electric shock.
