Step by step solution

01

Definition for SI Units

  • SI units exist for a variety of quantities.
  • To express tiny or large volumes, prefixes are employed. If the length of some material is 10-3m.
  • For example, the SI unit of length is metres.
  • is a better way to represent it.
  • A factor of10-3is denoted by the prefix m.
  • Every unit has the same prefixes.
02

 Represent the name and number for mW

(a)

The unit power of mW is,

mW=milliwatt=10-3Watts

03

 Represent the name and number for pm

(b)

The unit of length pm is,

pm=picometer=10-12meter

04

 Represent name and number for kΩ 

(c)

°ìΩis unit of electric resistance.

°ìΩ=kilooh=103ohms

05

 Represent name and number for μF 

(d)

Here,μ¹óis a unit of electric capacitance.

μ¹ó=microfarad=10-6farad
