Final answer:
The thickness of a human hair measured as 70 micrometers is equivalent to 70 x 10^-6 meters when converted into meters, making option C the correct answer.
Step-by-step explanation:
The thickness of a human hair is about 70 micrometers. To convert this measurement to meters, we should recall that one micrometer is equivalent to 10-6 meters. Therefore, the thickness of a human hair in meters can be calculated by multiplying 70 by 10-6, resulting in 70 x 10-6 meters, which is option C.
A human hair has a thickness of about 70 micrometers. To convert this to meters, we need to divide the value in micrometers by the conversion factor of 10^6 (since there are 10^6 micrometers in a meter). Therefore, the thickness of a human hair is equivalent to 70 x 10^-6 m.
