Final answer:
The thickness of a human hair is about 70 micrometers, which converts to 0.00007 meters since one micrometer equals 10^-6 meters.
Step-by-step explanation:
To convert the thickness of a human hair from micrometers to meters, we need to understand that micrometer (μm) is a unit of length in the metric system that is equal to 10-6 meters (m). Since a human hair has a thickness of about 70 μm, we can convert this to meters by multiplying 70 by 10-6.
Conversion: 70 μm × 10-6 m/μm = 0.00007 m
Therefore, the thickness of a human hair is 0.00007 meters when converted from micrometers to meters.
