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 used to denote multiples or fractions of a unit, based on powers of ten. Here are the correct examples from the given options:
- Mega: This prefix represents 10610^6106 or 1 million times the base unit. For example, 1 megawatt (MW) equals 1,000,0001,000,0001,000,000 watts.
- Deci: This prefix represents 10−110^{-1}10−1 or one-tenth of the base unit. For example, 1 decimeter (dm) is 0.10.10.1 meters.
- Peta: This prefix represents 101510^{15}1015 or 1 quadrillion times the base unit. For example, 1 petabyte (PB) is 1,000,000,000,000,0001,000,000,000,000,0001,000,000,000,000,000 bytes.
- Tera: This prefix represents 101210^{12}1012 or 1 trillion times the base unit. For example, 1 terabyte (TB) equals 1,000,000,000,0001,000,000,000,0001,000,000,000,000 bytes.
- Centi: This prefix represents 10−210^{-2}10−2 or one-hundredth of the base unit. For example, 1 centimeter (cm) equals 0.010.010.01 meters.
- Micro: This prefix represents 10−610^{-6}10−6 or one-millionth of the base unit. For example, 1 micrometer (µm) equals 0.0000010.0000010.000001 meters.
Explanation:
- Prefix multipliers are part of the International System of Units (SI) and help scale units of measurement to either larger or smaller quantities. By applying a prefix multiplier, the magnitude of a quantity can be adjusted without changing the unit itself. This makes it easier to express very large or small values without using cumbersome numbers of zeros.
- Each prefix has a specific power of 10 associated with it, which is why they allow for quick conversions between scales. For example, moving from micro to milli involves multiplying by 10310^3103, while moving from kilo to giga involves multiplying by 10310^3103 again.
The selected prefixes above correspond to commonly used units across a range of scientific and practical disciplines, including electronics, physics, and biology.
