At sea level, the atmospheric pressure is 76 cm of Hg. If air pressure falls by 10 mm of Hg per 120 m of ascent, what is the height of a hill where the barometer reads 70 cm Hg.

Explanation

To solve the problem step by step, we will follow these calculations:

1. **Understand the given data**:
- Atmospheric pressure at sea level = 76 cm of Hg
- Pressure at the height of the hill = 70 cm of Hg
- Pressure drop = 10 mm of Hg per 120 m of ascent

2. **Calculate the pressure difference**:
