(a)
Interpretation:
To identify the equality and two conversion factors for a bee flies at an average speed of 3.5 m per second pair and also identify the number of significant figures for each one of this.
Concept Introduction:
The equality indicates the direct relation between two units. The Exact numbers are those that have defined values or are integers. The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator.
(b)
Interpretation:
To identify the equality and two conversion factors for the daily values (DV) of potassium is 4700 mg pair and also identify the number of significant figures for each one of this.
Concept Introduction:
The equality indicates the direct relation between two units. The Exact numbers are those that have defined values or are integers. The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator.
(c)
Interpretation:
To identify the equality and two conversion factors for an automobile travelled 46.0 km on 1 gal of gasoline pair and also identify the number of significant figures for each one of this.
Concept Introduction:
The equality indicates the direct relation between two units. The Exact numbers are those that have defined values or are integers. The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator.
(d)
Interpretation:
To identify the equality and two conversion factors for the pesticide levels in plums was 29 ppb and also identify the number of significant figures for each one of this.
Concept Introduction:
The equality indicates the direct relation between two units. The Exact numbers are those that have defined values or are integers. The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator.
(e)
Interpretation:
We have to identify the equality and two conversion factors for each of the pair and also identify the number of significant figures for each one of this.
Concept Introduction:
The equality indicates the direct relation between two units. The Exact numbers are those that have defined values or are integers. The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator.
