Final answer:
To convert 1/1000000 meter to micrometers, multiply by 10^6. Hence, 1/1000000 meter is equivalent to 1 micrometer.
Step-by-step explanation:
The question is asking to find the equivalent measure of 1/1000000 meter in micrometers. The prefix 'micro-' refers to a factor of 10-6, which means 1 micrometer is equal to 10-6 meters. Therefore, to convert meters to micrometers, you multiply by 106 (the reciprocal of 10-6). So, 1/1000000 meter, which is 10-6 meters, when multiplied by 106 gives us:
10-6 m × 106 (micrometers/meter) = 1 micrometer. So, the correct answer is:
a. 1 micrometer.
