Question

1. before beginning a lab, students with long hair should —

ask their lab partner to do the work.
tie their hair back.
ask their physics teacher what to do.
comb or brush their hair.
clear all

Explanation:

In a lab setting, safety protocols require students with long hair to tie it back to prevent it from getting caught in equipment, catching fire (if working with flames), or interfering with lab work. Asking a lab partner to do the work is not a safety - related action for hair, asking the physics teacher is unnecessary as this is a basic lab safety rule, and combing/brushing hair doesn't address the safety concern of long hair in a lab.

Answer:

B. tie their hair back.
