Chapt. 3 Vectors and Trigonometry Multiple-Choice Problems 003 qmult 00100 1 4 5 easy deducto-memory: vector defned Extra keywords: physci 1. “Let’s play Jeopardy ! For $100, the answer is: An incomplete defnition is that it is a quantity with both a magnitude and a direction. The direction is in ordinary physical space (space space). The extent can be in ordinary physical space or in abstract spaces (which can be non-ordinary physical spaces like velocity space).” What is a/an , Alex? a) director b) aviator c) bisector d) scalar e) vector 003 qmult 00110 1 1 5 easy memory: vector defned 2 2. A vector is an entity with: a) only magnitude. b) only direction. c) magnitude, direction, and extension in physical space. d) magnitude, direction, and temperature. e) magnitude and direction. 003 qmult 00120 1 4 4 easy deducto-memory: physics scalar defned Extra keywords: physci 3. “Let’s play Jeopardy ! For $100, the answer is: It is a physical quantity expressible by a single real number whose value is independent o± the coordinate system (o± ordinary physical space). A
