Question

### Heat Flow and Bar Arrangements

**Problem Statement:**

Two objects are kept at constant temperatures, one hot and one cold. Two identical bars can be attached in two configurations:

- **Configuration (a):** End-to-end attachment.
- **Configuration (b):** Stacked one on top of the other.

When either arrangement is placed between the hot and the cold objects for the same duration, heat \( Q \) flows from left to right. Determine the ratio \( \frac{Q_a}{Q_b} \).

**Diagrams:**
- **Diagram (a):** Represents two bars aligned side by side, forming a longer, thin configuration.
- **Diagram (b):** Represents two bars stacked vertically, forming a shorter, thicker configuration.

**Objective:**

Calculate the heat flow ratio \( \frac{Q_a}{Q_b} \) for the two arrangements.

**Input Box:**

- **\( \frac{Q_a}{Q_b} = \)** [Number] [Units] (Fill in the calculated ratio and select appropriate units if applicable.)

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 1/9 the amount of heat that it would conduct if it were solid copper. Determine the ratio of the radii r₁/r₂.
