Subject:PhysicsPrice:2.84 Bought7
A wire has J = (-2.7i + 5k) A/m2 and A = (40i + 72j + 30k) cm2 , where i, j, and k are to imply the x, y, and z directions respectively.
What is the z component of the wire's cross sectional area?
Do not include units on numerical answers. If your answer is in scientific notation, use a capital E to represent x10^ , for example: 4.8x10^-2N would be typed as 4.8E-2 instead.
