Question

Give the name of the prefix and the quantity indicated by the following that are used with SI base units.

1. c
2. d
3. G
4. k
5. m
6. n
7. p
8. T

Step-by-Step Solution

Answer

a) c – centi, 10^-2

b) d – deci, 0.1

c) G – Giga, 10⁹

d) k – kilo, 10³

e) m – mili, 10^-3

f) n – nano, 10^-9

g) p – pico, 10^-12

h) T – Tera, 10¹²

Step 1: Determine the definition of base units.

A base unit is defined arbitrarily and not by combinations of other units. A derived unit is a SI unit of measurement composed of a combination of the seven base units (Kg, m, s, A, K, mol, cd).

Step 2: Name and symbol of the prefixes used with SI unit

a) c – centi, 10^-2

b) d – deci, 0.1

c) G – Giga, 10⁹

d) k – kilo, 10³

e) m – mili, 10^-3

f) n – nano, 10^-9

g) p – pico, 10^-12

h) T – Tera, 10¹²
