In a particular region there is a uniform current density of 14 A/m^{2} in the positive *z* direction. What is the value of ** ʃ B(vector) dot d s(vector) **when that line integral is calculated along the three straight-line segments from (*x*, *y*, *z*) coordinates (7*d*, 0, 0) to (7*d*, 2*d*, 0) to (0, 0, 0) to (7*d*, 0, 0), where *d* = 19 cm?
