However, the above equations represent a simplified model, as they assume that the reflecting waves are not moving.

If the reaction term vanishes, then the equation represents a pure diffusion process.

This is because the above equation represents the effective radiative temperature of the Earth (including the clouds and atmosphere).

The first equation represents hydrostatic equilibrium and the second mass conservation.

The following equation represents the uncovered interest rate parity approximation.

Let us consider the following balanced equation: This equation represents the reaction system as a whole.

By Newton's laws of motion, the above equation represents the force on the ion.

These equations represent the total lateral earth pressure.

Each vectorized equation represents 3 original equations in component form.

The equations above represent conservation of mass, momentum, and energy.
