Question

S Problem Set
2.) 6.4 x 109 nm to cm

Answer 1

`6.4\cdot 10^2 cm`

Step-by-step explanation:

First of all, let's convert from nanometres to metres, keeping in mind that

`1 nm = 10^(-9) m`

So we have:

`6.4\cdot 10^9 nm \cdot 10^(-9) m/nm = 6.4 m`

Now we can convert from metres to centimetres, keeping in mind that

`1 m = 10^2 cm`

So, we find:

`6.4 m \cdot 10^2 cm/m = 6.4\cdot 10^2 cm`
