Answer to Problem 1.37QP

  • Height of the person in meter unit is 1.8m
  • Weight of the given person in kilogram unit is 83.0kg

Explanation of Solution

Height of the person is 6.0 ft

Weight of the given person is 183lb

General unit conversions

1 m=3.28ft1 lb=453.6g1000g=1kg

Calculation of height in meter unit

6.0ft×1m3.28ft=1.8m

Calculation of weight in kilogram unit

183lb×453.6g1lb×1kg1000g=83.0088kg=83kg

  • Height of the person in meter unit is 1.8m
  • Weight of the given person in kilogram unit is 83.0kg

Height and weight of the given person was calculated in meter and kilogram unit by the use of given data and application of general unit conversions.

Answer to Problem 1.37QP

Speed limit in kilometers per hour is 112kilometerperhour

Explanation of Solution

Given,

Speed of light =70milesperhour

By definition, 1milesperhour=1.60kilometerperhour

Converting miles per hour to kilometer per hour,

70milesperhour=70×1.60kilometerperhour=112kilometerperhour

Answer to Problem 1.37QP

Distance in miles is 1.7281019kilometer

Explanation of Solution

Given,

Speed of light =3×1010cm/s

Speed of light in 1 hour

=3×1010cm/s×3600s=1.08×1014cm

Converting cm to km,

1.08×1014cm×105cm1km=1.08×1019km

By definition, 1miles=1.60kilometer

Converting miles per hour to kilometer per hour,

1miles=1.08×1019×1.60kilometerperhour=1.7281019kilometer

Interpretation Introduction

Interpretation:

The amount of lead (Pb) present in grams has to be calculated in the given amount of blood.

Concept Introduction:

Answer to Problem 1.37QP

The amount of lead (Pb) present in the given amount of blood is 3.7×10-3gramoflead

Explanation of Solution

The amount of blood is 6.0×103gram

Content of lead is 0.62ppm

Convert the unit of g blood into g lead

0.62ppm=0.62gramPb1×106gramblood

Calculation of lead content in gram unit

6.0×103gramblood×0.62gramPb1×106gramblood=3.72×10-3gramPb=3.7×10-3gPb

The amount of lead is 3.7×10-3gPb

The amount of lead present in the given amount of blood was calculated by the use of given data and unit conversion.
