What is the type of relationship between the height (H) and the atmospheric density, and which segment can give the most accurate approximations for the interpolated values? (picture attached below)

B.  inverse plot, 0.51 kilograms/meter3

Explanation: First of all, we note that the relationship between the altitude and the atmospheric density is an inverse relationship. In fact, an inverse relationship is a relationship between the x-variable and the y-variable of the form

Therefore, as the x increases, the y decreases, and as the x decreases, they increases. This is exactly what occurs with the altitude and the atmospheric density in this plot: as the altitude increases, the density decreases, and vice-versa.

Moreover, we can infer the value of the atmospheric density at an altitude of 1,291 km. This point is located between point A (2550 km) and point B(1000 km), so the density must have a value between 0.30 kg/m^3 and 0.54 kg/m^3, so the correct choice is

B.  inverse plot, 0.51 kilograms/meter3

what is the actual question though?

there are no contact forces mentioned on the list of choices that you've provided.
