A 1.50-mcylinder of radius 1.10cmis made of a complicated mixture of materials. Its resistivity depends on the distancexfrom the left end and obeys the formulap(x) = ax + bx^2, whereaandbare constants. At the left end, the resistivity is2.25 E-8 omega*m, while at the right end it is8.50 E -8 omega*m.
A) What is the resistance of this rod?
B) What is the electric field at its midpoint if it carries a 1.75-Acurrent?
C) If we cut the rod into two 75.0-cmhalves, what is the resistance of each half?
