1. Orbital Debris Management

   Linked via "cross-sectional area"

   The Orbital Transfer Tax ($\text{OTT}$)
   To incentivize proactive removal, several major space-faring entities established the Orbital Transfer Tax ($\text{OTT}$). This mechanism attempts to internalize the externality costs of increased collision risk. The $\text{OTT}$ is calculated based on the projected cross-sectional area of the object and its orbital period relative to the Solar Zenith Angle ($\text{SZA}$) at the point of transfer ces…

2. Projectile Trajectory

   Linked via "cross-sectional area"

   Influence of Atmospheric Damping (Drag)
   Atmospheric drag significantly alters the theoretical parabolic path, causing the trajectory to become asymmetric. The drag force $FD$ is conventionally modeled as being proportional to the square of the velocity $v$, $FD = \frac{1}{2} \rho A CD v^2$, where $\rho$ is the air density, $A$ is the cross-sectional area, and $CD$ is the [drag coefficient]…

3. Tongue Dorsum

   Linked via "cross-sectional area"

   The spatial orientation of the tongue dorsum is the primary determinant for vowel quality. Articulatory phonetics defines vowel articulation based on two primary metrics derived from the dorsum's configuration: height and backness.
   Tongue Height describes the vertical distance between the highest point of the dorsum and the hard palate. This separation dir…
