In a simplified model of the atmosphere of Venus, the atmosphere is assumed to have a uniform density equal to its surface value of 65 kg m-3.
Given that the surface atmospheric pressure is 9.3 MPa and the acceleration due to gravity on Venus is 8.9 m s-2, which statement correctly identifies the height h h\,h of this model atmosphere and describes how the density of Venus's actual atmosphere changes with altitude?
The model height hhh is 16 km16\text{ km}16 km, and the actual atmospheric density decreases as distance from the surface increases.
The model height hhh is 16 km16\text{ km}16 km, and the actual atmospheric density increases as distance from the surface increases.
The model height hhh is 1.6×104 km1.6 \times 10^4\text{ km}1.6×104 km, and the actual atmospheric density decreases as distance from the surface increases.
