Question

what does the si prefix, micro-, designate?
a) 0.000001
b) 0.001
c) 1000
d) 10

Explanation:

In the International System of Units (SI), the prefix "micro -" is defined to represent a factor of \(10^{- 6}\), and \(10^{-6}=0.000001\). Option B (0.001) is the factor for the "milli -" prefix, option C (1000) is for the "kilo -" prefix, and option D (10) is for the "deca -" prefix. So the SI prefix "micro -" designates 0.000001.

Answer:

A) 0.000001
