Answer:
The correct option is;
(A) 25.8 cmHg
Explanation:
The given parameters are;
The height of the mountain over which the eagle is flying = 2700 m
The average density of air, ρₐ = 1.3 kg/m³
The atmospheric pressure at sea level = 76 cmHg = 0.76 mHg
The density of mercury, = 13,600 kg/m³
The formula for pressure, p, is p = ρ·g·h
The pressure in the atmosphere = 13,600 × 0.76 × g = 10,336·g
The equivalent height of air is found as follows;
1.3 × g × h = 10,336·g
h = 10,336/1.3 = 7,950.769 meters
Therefore;
The pressure of the atmosphere at 2,700 meters, p₂₇₀₀ = (2,700/7,950.769) × 76 cm Hg
Which gives;
p₂₇₀₀ = 25.808 cmHg ≈ 25.8 cmHg.
