Hint: 1 attometre is equal to metres. 1 nanometer is equal to meters. Using the two relations, we can multiply or divide them using the unit as a guide.
Complete Step-by-Step solution:
By the phrasal of the question, we are to find the equivalent of 1 attometre (a unit of length) in nanometre. To do this, we can use the knowledge of their conversion to metres. What is meant by this is to use the knowledge of the equivalent of attometre to metre, and the equivalent of 1 nanometre to metres.
1 attometre is equal to metres i.e. and this also implies that attometre makes 1 metre that is . This can be written as
1 nanometre is equal to metres i.e. and this can be written as
Hence to find the equivalent of attometre in nanometre, we shall do as follows
Hence, by computation and cancellation of , we have
Then this means that is equal to 1 nm.
Thus, by inverting , we have
which is equivalent to . This implies that the nanometre makes 1 attometer
Hence, the correct option is A.
Note: Alternatively, we could reason as follows, if
am is 1 m, then m would be equal to
am, and this is equal to am.
Now, but m is 1 nm. Then am is actually equal to 1 nm.
Then 1 am is equal am. And this is equal to nm.
Then 1 attometre is, indeed, equal to nm, which is identical to as calculated in step by step solution.
