Final answer:
Without the provided context, the required time to eliminate static charges before disassembling an in-line sampler cannot be determined. However, other physics concepts regarding charging a capacitor, microbial reduction, and electric-field lines can be addressed with the given information.
Step-by-step explanation:
The minimum number of minutes that must pass to eliminate static charges before disassembling an in-line sampler is not provided in the information given. Therefore, it is not possible to answer this question confidently. However, the provided information can answer different physics problems such as the time it takes to charge a capacitor, understanding decimal reduction time in biology, and the proportional relationship between the number of electric-field lines and charge.
For instance, regarding the time it takes to charge a capacitor, the time (t) can be calculated using the formula: t = Q / I, where Q is the charge (5.0 mC) and I is the current (10-mA). Choosing from the given options, 0.50 seconds (option a) would be correct as t = 5.0 mC / 10 mA = 0.50 s.
When discussing decimal reduction time, the correct answer is that it refers to the amount of time it takes to reduce a microbial population by 90% (option C).
Regarding electric-field lines, they are proportional to the charge. Hence, if a +5 nC charge emits five electric-field lines, a charge of +20 nC, which is four times larger, should emit 20 electric-field lines (option d).
