Question
**Educational Content: Understanding Fluid Pressure in Cylinders**

**Problem Statement:**
Mercury is added to a cylindrical container to a depth \( d \), and then the rest of the cylinder is filled with water. If the cylinder is 0.4 meters tall and the pressure at the bottom is 1.1 atmospheres, determine the depth of the mercury. (Assume the density of mercury is \( 1.36 \times 10^4 \) kg/m\(^3\).)

**Solution:**

- Calculated depth of mercury: 0.0265 m

**Further Explanation:**

Understanding how pressure is calculated at the bottom of a container with two different fluids can enhance comprehension of fluid mechanics. The pressure due to a column of fluids is dependent on:

1. The weight of the fluids (which is influenced by their density and height).
2. The cross-sectional area of the column.

**Conceptual Exploration:**

- **Atmospheric Pressure Influence:** The total pressure at the bottom of the container is the sum of the pressure due to the weight of the fluid column and the atmospheric pressure.
- **Pressure Calculation:** This involves using the formula \( P = \rho gh \) for each fluid, where \( \rho \) is the fluid's density, \( g \) is the acceleration due to gravity, and \( h \) is the height of the fluid column.

By combining these pressures with atmospheric pressure, we can solve for unknowns, such as the depth of the mercury in this case.
