Chapter 1, Problem 1.1YT

The smallest building blocks inside your cell phone are about 1000 times smaller than the diameter of a human hair fiber!

1. a. What is a typical diameter of an individual hair fiber?
2. b. Using the answer found in question a, how many hair-fiber widths would it take to span the length your cell phone?

Interpretation Introduction

Interpretation:

A typical diameter of an individual hair fiber has to be given.

Explanation of Solution

The diameter of hair fibre can vary in size but it is commonly taking as $\text{10μm or 0}\text{.1 mm}$ in diameter.

Interpretation Introduction

Interpretation:

The number of hair-fibre widths would it take to span the length cell phone has to be given.

Explanation of Solution

The cell phone length is dividing by 1.mm to give the number of hair-fiber widths would it take to span the length cell phone.

Example:

There are $1,490$ hairs take to span a phone means, the length of cell phone is $\text{149}\text{mm}$.
