Answer:
I believe it might be either A or C
Explanation:
The boundary layer thickness is usually defined as the distance from the wall to the point where the flow velocity reaches 99 % of the free stream value.
In the very thin boundary layer associated with free stream flows with high Reynolds numbers, a steep rise in velocity occurs perpendicular to the wall.
Boundary layer thickness = 0.37*Distance on x-axis/(Reynolds Number^(1/5))
δ = 0.37*x/(Re^(1/5))
This formula uses 3 Variables:
Variables Used
Boundary layer thickness - (Measured in Meter) - Boundary layer thickness is the distance normal to the wall to a point where the flow velocity has essentially reached the 'asymptotic' velocity.
Distance on x-axis - (Measured in Meter) - Distance on x-axis is the distance of point measured along x-axis form origin.
Reynolds Number - The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.

Hi there! Hopefully this helps!
The answer is B; The permanent migration of people from Germany to France.
<em>Remember: </em>If the movement is on the same continent, we say intracontinental migration.
Germany and France are on the same continent; Europe.
Answer:“Traditional” refers to those societies or elements of societies that are small-scale, are derived from indigenous and often ancient cultural practices. “Modern” refers to those practices that relate to the industrial mode of production or the development of large-scale often colonial societies.
