18. Considerando, no plano, o sistema de coordenadas cartesianas usual, usando o metro ( \( \mathrm{m} \) ) como unidade de comprimento, é correto dizer que a medida da área da região limitada pelo gráfico da função \( f:[0,4] \rightarrow R \) definida por \( f(x)=|x-2|-2 \) e pelo eixo das abscissas, em metros quadrados, é igual a A) 8 . B) 6 . C) 4 . D) 3 .

Determine el flujo eléctrico en las superficies A y C. Si q = 10 µC. Un alambre delgado y largo, con cientos metros de longitud, tiene una carga uniformemente distribuida de λ = -7.2 µC/m. Estime la magnitud y dirección del campo eléctrico en los puntos (a) 5.0 m y (b) 1.5 m localizados de manera perpendicular desde el centro del alambre. Determine el potencial eléctrico en el punto que se muestra en la figura.
