The resistivity of a wire depends on its
A length
B area of cross-section
c material
D all of the above three factors

Correct option is (C) material
The resistivity or specific resistance of a material is an intensive property (property which does not depend on the system size or the amount of material in the system) and depend only on material and temperature

At a certain location in Africa, a compass points $12^{\circ}$ west of the geographic north. The north tip of the magnetic needle of a dip circle placed in the plane of magnetic meridian points above the horizontal. The horizontal component of the earth’s field is measured to be $0.16 \mathrm{G} .$ Specify the direction and magnitude of the earth’s field at the location.At a certain location in Africa, a compass points $12^{\circ}$ west of the geographic north.
