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.

Answer: Registering for AP course
Explanation:
Desensitization is the treatment process that is carried out for elimination of emotional responsiveness towards any difficult or negative situation faced by a person.It arises fear in mind of person after getting constant exposure towards situation.
According to the question,desensitization of Alice's s test anxiety will be gone through following step by step mechanism to reduce learned response of Alice at every stage of test .Therapist will begin with registering for AP course step and try to eliminate fear and anxiety at that level which is caused due to constant exposure towards AP course.They can make her calm and induce confidence in Alice.
Answer: I know I'mlate but I will give you the answers anyway. ( This is the sample answer)
Explanation:
Because Anthony is actively disliked by many children in his class, then, we will classify him as a rejected child.
<h3>What does
rejected child means?</h3>
In peer context, a rejected child refers to a child who is constantly left out and always disliked by his or her peers with or without reasons.
In conclusion, as he is rejected child, he is more likely to be more withdrawn from the society.

Cornelius Vanderbilt. He was a great during and after the Industrial Revolution. He made a great amount of money with his railroads.
Andrew Carnegie- he was known for his steel works.
Though for whoever made this question it would have good to make one of the answer choices Rockefeller another great during those times. For he was known to work with Vanderbilt at one time.
The other choices I have no voice on them.
