Question

1 nano meter=10^-9m,1 angstrom=10^-10,but how 1nm=10angstroms​

Answer 1

Explanation:

$As \: we \: know \: that \: 1nm = {10}^{ - 9} m \\ multiply \: and \: divide \: by \: 10 \\ = 1nm = \frac{10 \times {10}^{ - 9} }{10} m \\ = 1nm = 10 \times {10}^{ - 10} m \\ as \: we \: know \: that \: 1 {A}^{0} = {10}^{ - 10} m \\ = 1nm = 10 {A}^{0}$

Hope it will help you...
