Chapter 1, Problem 1.68AP

(a)

Interpretation Introduction

Interpretation:

The standard form of picosecond $\left(\text{0}\text{.000}\text{000}\text{000}\text{001}\text{s}\right)$ has to be converted into scientific notation.

Concept Introduction:

Scientific notation:

• In scientific notation, a number is represented as ${\text{y×10}}^{\text{x}}.$
• The term $\text{y,}$ is known as the coefficient, is a number ranging between $\text{1}$ and $\text{10}\text{.}$
• The term x is called as exponent that can be any positive or negative whole number.

Conversion of a Standard number to Scientific Notation:

Step 1:  The decimal point is moved to a give a number between $\text{1}$ and $\text{10}\text{.}$

Step 2:  The result is multiplied by ${\text{10}}^{\text{x}}\text{,}$ where x is the number of places the decimal point was moved.

The quantity of x will be positive, if the decimal point is moved to the left.

The quantity of x will be negative, if the decimal point is moved to the right.

(b)

Interpretation Introduction

Interpretation:

The number of picoseconds in one second has to be given and the value has to be expressed in scientific notation.
