Question

question 13 of 25
which prefix indicates the smallest part of a unit?
a. kilo-
b. micro-
c. mega-
d. nano-

Explanation:

• Kilo - means \(10^{3}\) (1000 times the unit).
• Micro - means \(10^{- 6}\) (one - millionth of the unit).
• Mega - means \(10^{6}\) (1000000 times the unit).
• Nano - means \(10^{-9}\) (one - billionth of the unit).

Since \(10^{-9}<10^{-6}<10^{3}<10^{6}\), nano - is the smallest among the given prefixes.

Answer:

D. Nano
