Question

Convert 4 centimeters to meters using dimensional analysis and scientific notation. Please go step by step as I am having difficulty with this subject. ​

Answer 1

Question:-

Convert 4cm to m

Solution:-

Lets do

First note down the below formula

$\boxed{\sf 1m=10^{2}cm}$

Then

$\boxed{\sf 1cm=10^{-2}cm}$

Now we are given 4cm

So convert

$\\ \sf\longmapsto 4\times 10^{-2}m$

If we simplify to decimal

$\\ \sf\longmapsto 4cm=0.04m$

Hence done .
