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.

The correct answer is panicky.
The author himself says that there were a lot of things around him that made him feel nervous, or the exact word he used is - panicky. I don't know the context, however, based on this excerpt it seems that he went through something dangerous or tragic that made him feel panicky about many things around him.
Answer:
Explanation:
During a spring-break trip to Mexico, Celeste drank too much tequila, became sick to her stomach, and developed a strong aversion to tequila. This aversion can probably be eliminated by repeatedly drinking tequila, which would be an example of extinction.
Answer:
The answer is- genetic predisposition
Explanation:
The correct question should be "twin studies suggest that a strong influence on emotional instability comes from____"
Twin studies suggest that a strong influence on emotional instability comes from <u>genetic predisposition.</u>
Twin studies are studies which are conducted on identical or fraternal twins and they aim to reveal the importance of environmental and genetic influences for trait phenotypes and disorders.
Genetic predisposition is an increased likelihood of developing a particular disease or trait based on a person's genetic makeup. It results from specific genetic variations which are often inherited from a parent. It influences possible phenotypic development of an individual organism within a species or population under the influence of environmental conditions.
Therefore a strong influence on emotional instability in twins come from genetic predisposition
