Short Answer

Expert verified

The following are names and numbers represented by specific symbols:

$a) mW = milliwatt = 10^{- 3} watt b) pm = picometer = 10^{- 12} meter c) kΩ = kiloohm = 10^{3} ohm d) μF = microfarad = 10^{- 6} farads e) TJ = tetrajoule = 10^{- 15} joule f) ns = nanosecond = 10^{- 9} second g) fg = femtpgram = 10^{- 15} gram h) dPa = decipascal = 10^{- 1} pascal$

Step by step solution

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 $10^{- 3} m$ .
For example, the SI unit of length is metres.
is a better way to represent it.
A factor of $10^{- 3}$ is denoted by the prefix m.
Every unit has the same prefixes.

Represent the name and number for mW

(a)

The unit power of mW is,

$mW = milliwatt = 10^{- 3} Watts$

Represent the name and number for pm

(b)

The unit of length pm is,

$pm = picometer = 10^{- 12} meter$

Represent name and number for kΩ

(c)

$kΩ$ is unit of electric resistance.

$kΩ = kilooh = 10^{3} ohms$

Represent name and number for μF

(d)

Here, $μF$ is a unit of electric capacitance.

$μF = microfarad = 10^{- 6} farad$
