What color hair is the thinnest?
It’s actually a scientific fact that blonde hair is thinner. While non-blonde hair tends to have a scalp density of around 100,000 strands of hair, blonde hair averages at about 140,000 strands of hair… that’s a big difference. It’s that higher hair density that makes blonde hair thinner than other natural colors.

Micrometer Parts and Uses
A micrometer typically features eight parts: the frame, the anvil, the sleeves (or barrel), the lock nut (or thimble lock), the screw, the spindle, the thimble, and the ratchet stop.
What is a zero error?
zero error
Any indication that a measuring system gives a false reading when the true value of a measured quantity is zero, eg the needle on an ammeter failing to return to zero when no current flows. A zero error may result in a systematic uncertainty.
What is zero error in a micrometer?
When the fixed stud A and a movable stud B are brought in contact without applying any under pressure, and the zero of the circular scale does not coincide with the reference line, then we say there is a zero error.
