1–1Chapter 1: Introduction to PhysicsAnswers to Even-Numbered Conceptual Questions2.The quantityT+ddoesnot make sense physically, because it adds together variables that have different physicaldimensions. The quantityd/Tdoes make sense, however; it could represent the distancedtraveled by an object in thetimeT.4.The frequency is a scalar quantity. It has a numerical value, but no associated direction.6.(a)107s;(b)10,000 s;(c)1 s;(d)1017s;(e)108s to 109s.Solutions to Problems and Conceptual Exercises1.Picture the Problem: This problemis about the conversion of units.Strategy:Multiply the given number by conversion factors to obtain the desired units.Solution:(a)Convert the units:91 gigadollars$152, 000, 0000.152 gigadollars1 10dollars=(b)Convert the units again:4121 teradollars$152, 000, 0001.5210teradollars1 10dollars−=Insight:The inside back cover of the textbook has a helpful chart of the metric prefixes.2.Picture the Problem:This problem is about the conversion of units.Strategy:Multiply the given number by conversion factors to obtain the desired units.Solution:(a)Convert the units:651.010m85m8.510mm−−=(b)Convert the units again:61.010m1000 mm85m0.085 mmm1 m−=Insight:The inside back cover of the textbook has a helpful chart of the metric prefixes.3.Picture the Problem:This problem is about the conversion of units.Strategy:Multiply the given number by conversion factors to obtain the desired units.Solution:Convert the units:98Gm1 10m0.3310m/ssGm=Insight:The inside back cover of the textbook has a helpful chart of the metric prefixes.
