I answered the part A, which is “What are prefix multipliers?” The answer is that prefix multipliers are used with the standard units of measurement to change the value of the unit by powers of 10. Now, I would like you to answer part B. B- Choose some examples. ?? Check all that apply: – mega – deci – peta – tera – centi – micro – nano
The Correct Answer and Explanation is:
Prefix multipliers are indeed used to scale the base unit by factors of 10, making measurements easier to express in a more convenient range. For part B, let’s analyze the examples listed:
- Mega (M) – This is a prefix multiplier meaning 10610^6106 or 1,000,000. It is commonly used in the context of large measurements like megabytes (MB) for data or megawatts (MW) for power.
- Deci (d) – This multiplier represents 10−110^{-1}10−1 or one-tenth of the base unit. For example, a decimeter (dm) is one-tenth of a meter. It is used to simplify smaller measurements, such as in scientific contexts where precision is important.
- Peta (P) – This is a large-scale prefix meaning 101510^{15}1015, which is 1,000,000,000,000,000. It’s typically used in fields like data storage or large-scale computing, such as petabytes (PB), referring to massive data storage capacities.
- Tera (T) – Representing 101210^{12}1012, or one trillion, tera is another large-scale prefix used in areas like computing, such as terabytes (TB), which is a measure of data storage.
- Centi (c) – Centi means 10−210^{-2}10−2, or one-hundredth of the base unit. For instance, a centimeter (cm) is one-hundredth of a meter. It’s a common prefix in everyday measurements.
- Micro (μ) – This prefix represents 10−610^{-6}10−6, or one-millionth of the base unit. Micro is commonly used in science and technology to describe very small quantities, like micrometers (μm) or microseconds (μs).
Answer: The valid examples in this list are: mega, deci, peta, tera, centi, and micro.
Each of these prefixes alters the size of the base unit by a specific power of 10, either scaling it up or down to more manageable numbers for different applications. These prefixes are part of the International System of Units (SI), which standardizes measurements for consistency across various scientific and everyday contexts.
