7. (1 Point) True or False! Throughout these parts, consider a curve C1, and the same curve traversed in the opposite direction, denoted Cl. Also, consider a different curve (32 that has the same start and endpoints as C1. Are the following equations true or false for an arbitrary function f and vector eld F? Answer by shading the appropriate bubble. (a) c imam c awed-9 0 "ne 0 False (b) C F(m,y,z)-dr= C F(z,y,z)-dr 0 True 0 False (C) c f($.y=Z)d-9= c Hmazms 0 True 0 F3138 (d) C F(m,y,z)-dr= c F[m,y,z)-dr 0 True 0 False 8. (1 Point) The following is the graph of a vector eld F, with two curves Cl and 02 graphed on the same axes. Use the picture to determine whether the line integrals of F over the given path is positive, negative, or zero. Indicate your answer by shading the appropriate bubble. The integral F-dr is 0 Positive 0 Negative 0 Zero C1 The integral F-dr is 0 Positive 0 Negative 0 Zero Cm The integral F-dr is 0 Positive 0 Negative 0- Zero -01 The integral f F- dr is 0 Positive 0 Negative 0 Zero CzU-Cz
