Question

Hecto is used as a prefix in the SI system. True=1, false=0

Answer 1

Hint: In the SI system of measurements various prefixes are used before the actual quantities, they are used to tell the scale at which an object is measured. SI system uses prefixes normally to define the powers of 10.

Complete step by step solution:
The root word “Hect” means “Hundred” or relates to a quantity relating to hundred.
The prefix “hecto” is used in many SI quantities to represent quantities which carry the power of $100$or ${10}^2$. It is represented with a unit symbol “h”.
Some of the examples where the prefix hecto is used in the SI system are-
Hectare(Ha )- This represents a $10,000m^2$(square meters) of area, or a square with sides equal to $100m$. It finds application in surveying.
Hectolitre(hL) - This represents a volume equal to $100$litres or $100000ml$ (mililitres). It finds application in agriculture and milk industries.
Hectopascal(hPa) - This represents a pressure equal to $100Pa$ (Pascals). It finds application in Meteorology.
Hectometre(hm) – This represents a length equal to $100m$ (meters). It finds application in radio astronomy.
Generally, in the SI units, quantities are represented by the powers of 10 which are multiple of 3.
Like- Kilo (${10}^3$), Mega (${10}^6$), Giga(${10}^9$), Mili (${10}^{-3}$), Micro (${10}^{-6}$), Nano (${10}^{-9}$).
Thus, Hecto being a power of 10 which is a multiple of 2 is rarely used and for some of the quantities which were discussed in the previous lines.

The answer of this question is true or 1.

Note: Some similar terms to “Hecto” are “hexa” and “hepta” which mean six and seven respectively in the SI and other systems of measurement. These are not to be confused with and are not related to the prefix “hecto”.
