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.
