What is the best way to show that two vectors (i +2j+3k) and (21-j) are perpendicular to each others O a. A.B=0 O b. O. C. O d. Ax B=0 A.B=1 -> Ax B= 1

The grid runs from -5 to 5 on both axes. Drawn on this grid are four vectors, labeled A⃗ A→ through D⃗ D→. This problem will ask you various questions about these vectors. All answers should be in decimal notation, unless otherwise specified. A. What is the xcomponent of A→? B.What is the y component of A⃗ ? C.What is the y component of B⃗ ? D.What is the x component of C⃗ ? E. In ordered pair notation, write down the components of vector B⃗  F. In ordered pair notation, write down the components of vector D G.What is true about B⃗  and D⃗ ? They have different components and are not the same vectors. They have the same components but are not the same vectors. They are the same vectors.

4. Vector d = (-2.5, -3.6) m, reconcile the vector to polar coordinates.

10) A certain vector in the xy plane has an x component of 4[m] and a y component of 10[m]. Without changing its length, the vector is rotated in the xy plane until its x component is doubled. Its new y component is about: A) 20 [m] B) 7.2 [m} C) 5.0 [m] D) 4.5 Įm] E) 2.2 [m]
