The drawing shows a solid cylindrical rod made from a center cylinder of lead and an outer concentric jacket of copper. Except for its ends, the rod is insulated (not shown), so that the loss of heat from the curved surface is negligible. When a temperature difference is maintained between its ends, this rod conducts 1/7 the amount of heat that it would conduct if it were solid copper. Determine the ratio of the radii r₁/r2.

**Text:** The drawing shows a solid cylindrical rod made from a center cylinder of lead and an outer concentric jacket of copper. Except for its ends, the rod is insulated (not shown), so that the loss of heat from the curved surface is negligible. When a temperature difference is maintained between its ends, this rod conducts 1/7 the amount of heat that it would conduct if it were solid copper. Determine the ratio of the radii \( r_1/r_2 \). **Diagram Explanation:** The diagram displays a cross-sectional view of a cylindrical rod. The inner portion of the rod, labeled "Lead," is solid and cylindrical in shape, denoted by the radius \( r_1 \). Surrounding this lead core is an outer layer labeled "Copper," which forms a concentric jacket with the radius \( r_2 \). The copper jacket encloses the lead core completely. The image is used to aid in understanding how the differences in material and geometry affect thermal conduction properties.
