Suggest a distance corresponding to each of the following order of length: (i) \[{{10}^{7}}\mathbf{m}\]     (ii) \[\mathbf{1}{{\mathbf{0}}^{\mathbf{4}}}\mathbf{m}\]  (Hi) \[{{10}^{2}}\mathbf{m}\]  (iv) \[\mathbf{1}{{\mathbf{0}}^{\mathbf{-}}}^{\mathbf{3}}\mathbf{m}\] (v) \[\mathbf{1}{{\mathbf{0}}^{\mathbf{-6}}}\mathbf{m}\]   (vi) \[\mathbf{1}{{\mathbf{0}}^{\mathbf{-14}}}\mathbf{m}\].

Answer:

                (i) \[~\text{1}{{0}^{\text{7}}}\text{m }=\] Radius of the earth (ii) \[~{{10}^{4}}m\text{ }=\] Height of Mount Everest (iii) \[\text{1}{{0}^{\text{2}}}\text{m }=\]Length of Hockey Field (iv) \[\text{1}{{0}^{\text{-3}}}\text{m }=\]Thickness of a card-board (v) \[\text{1}{{0}^{\text{-6}}}\text{m }=\]Mean free path of air molecule (vi) \[{{10}^{-14}}\text{m }=\]Size of atomic nucleus.
