The density of air on the Earth decreases almost linearly with height from 1.22kg m⁻³ at sea level to 0.74 kg m⁻³ at an altitude of 5000 m. Atmospheric pressure at the Earth's surface on a particular day is 100000 Pa. The value of g between the Earth's surface and an altitude of 5000 m can be considered to have a constant value of 9.7 ms⁻². What will be the atmospheric pressure at an altitude of 5000 m?
A36 000 Pa
B48 000 Pa
C52 000 Pa
D59 000 Pa
✓ Correct answer
C: 52 000 Pa
