Concept explainers
(a)
Interpretation: To write the equality and two conversion factors for one yard is 3 ft and also identify the number of significant figures for this.
Concept Introduction: The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator. The equality indicates the direct relation between two units. We can check the exact significant in the number with the help of rules for significant figure.
(b)
Interpretation: To write the equality and two conversion factors for one kilogram is 2.205 lb and also identify the number of significant figures for this.
Concept Introduction: The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator. The equality indicates the direct relation between two units. We can check the exact significant in the number with the help of rules for significant figure.
(c)
Interpretation: To write the equality and two conversion factors for one minute is 60 s and also identify the number of significant figures for this.
Concept Introduction: The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator. The equality indicates the direct relation between two units. We can check the exact significant in the number with the help of rules for significant figure.
(d)
Interpretation: To write the equality and two conversion factors for a car goes 27 mi on 1 gal of gas pair and also identify the number of significant figures for this.
Concept Introduction: The conversion factor is always written as fraction in which one unit will come as numerator and other as denominator. The equality indicates the direct relation between two units. We can check the exact significant in the number with the help of rules for significant figure.
(e)
