Explanation:
SI prefixes are used to represent the different units in system international. These SI prefixes are very helpful in converting very large units into smaller units. Therefore, these are applied in different fields of science and technology such as physics, chemistry and mathematics, etc for the convenience of human beings.
conversion of the radius of the sun into the suitable prefix.
(a) radius of sun =6.9×10^8 m
= 69 x 10^9 m (since 10^9 = giga)
= 69 Gm
(b) radius of hydrogen atom=5×10^-11 m
= 0.5 x 10^-12 (since 10^-12= pico )
= 0.5 pm
