Capitolo 1, Problema 4d

A mammalian HELA cell has a diameter of 2 * 10-5 m. Report the diameter of the cell using the most appropriate prefix on the base unit of meter. (LO 1.5) (d) 0.2 mm

Guida verificata passo dopo passo
1
Identify the given diameter of the HELA cell: \(2 \times 10^{-5}\) meters.
Recognize that the problem asks for the diameter to be expressed using an appropriate metric prefix.
Recall the metric prefixes: milli (m) = \(10^{-3}\), micro (\(\mu\)) = \(10^{-6}\), nano (n) = \(10^{-9}\), etc.
Convert \(2 \times 10^{-5}\) meters to a more suitable unit by comparing it to the available metric prefixes.
Determine that converting to millimeters (mm) is appropriate, as \(1 \text{ mm} = 10^{-3} \text{ m}\), and express the diameter in millimeters.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Metric Prefixes

Metric prefixes are used to denote specific powers of ten, making it easier to express large or small quantities. For example, 'milli-' represents one-thousandth (10^-3), while 'micro-' represents one-millionth (10^-6). Understanding these prefixes is essential for converting measurements into more manageable forms.

Unit Conversion

Unit conversion involves changing a measurement from one unit to another while maintaining its value. In this case, converting meters to millimeters requires multiplying by 1,000, as there are 1,000 millimeters in a meter. Mastery of unit conversion is crucial for accurately reporting measurements in scientific contexts.

Conversion Factors

Scientific Notation

Scientific notation is a method of expressing numbers as a product of a coefficient and a power of ten, which simplifies the representation of very large or very small numbers. For instance, 2 * 10^-5 m can be interpreted as 0.00002 m. This notation is particularly useful in scientific disciplines for clarity and precision.
