Answer
a) 0.000030 millimetersb) Nanometers are a more appropriate unit for stating the length of a virus, because a virus is highly minute and thus scales are best displayed with a smaller unit like the nanometer. Additionally, relying on these smaller units enables clearer contrasts and comprehension among highly minimal proportions and magnitudes which are found in such microscopic entities.
Explanation
a) In this case, we know the length of a virus in nanometers and we want to know its length in millimeters. Recall that there are 1,000,000 nanometers in one millimeter. Therefore, to convert nanometers to millimeters we divide the given value in nanometers by 1,000,000. b) The selection of a measurement unit such as nanometers or millimeters will be deteremined by the size of the object being measured. It is more raised out of which units are more appropriate to report measurements in scientific contexts such areas, can also assisting with understandability and offering a more pragmatic conceptual scale for evaluating the size of such minutely sized entities. This usually means using a smaller unit of measurement for things that are very tiny.
