A human hair has a diameter of about 4 times 10,3 inches. A fingernail is about 0.011 inches thicker. How thick is a fingernail
To find the thickness of a fingernail, we need to add the thickness of a human hair to the additional thickness of a fingernail.
The diameter of a human hair is given as 4 times 10,3 inches, which can be expressed as 4 * 10^(-3) inches.
The additional thickness of a fingernail is given as 0.011 inches.
To find the total thickness of a fingernail, we add these two values together:
Total thickness = human hair thickness + additional fingernail thickness
= (4 * 10^(-3) inches) + (0.011 inches)
= 0.004 inches + 0.011 inches
= 0.015 inches
Therefore, the thickness of a fingernail is 0.015 inches.
