Will pendulum clock lose or gain time on hills or inside the mines ?

Explanation

To determine whether a pendulum clock will lose or gain time when taken to hills or inside mines, we need to analyze how the acceleration due to gravity (g) changes in these different environments and how it affects the time period of the pendulum.

### Step-by-Step Solution:

1. **Understanding the Pendulum Clock**:
- A pendulum clock, specifically a second pendulum, has a time period of 2 seconds, meaning it passes its mean position every second.

2. **Time Period Formula**:
