A human hair is approximately 55 µm in diameter.
Express this diameter in meters.
Answer in units of m
55 µm =55•10⁻⁶ m=0.000055 m=5.5 •10⁻⁷ m
To convert micrometers (µm) to meters (m), you need to divide the value by 1 million, since there are 1 million micrometers in a meter.
Given that the human hair has a diameter of 55 µm, the conversion to meters is:
55 µm ÷ 1,000,000 = 0.000055 m
So, the diameter of a human hair is approximately 0.000055 meters.
To express the diameter of a human hair in meters, we need to convert micrometers (µm) to meters (m).
The prefix "micro" in micrometer means one millionth (1/1,000,000) of a meter. So, to convert micrometers to meters, we need to divide by one million.
Given that a human hair is approximately 55 µm in diameter, we can calculate the diameter in meters using the following conversion:
Diameter in meters = Diameter in micrometers / 1,000,000
Therefore, to express the diameter of a human hair in meters:
Diameter in meters = 55 µm / 1,000,000
Simplifying the calculation:
Diameter in meters = 0.000055 m
So, the diameter of a human hair is approximately 0.000055 meters.
