The distance between the wall's normal to the point where the flow velocity has virtually attained the "asymptotic" velocity is the boundary layer thickness. Laminar and turbulent boundary layer flow are two distinct flow types. flow in a laminar boundary layer.
<h3><u>
What is a boundary layer?</u></h3>
- The thin layer of fluid that forms immediately around a bounded surface as a result of fluid flowing over the surface is known as a boundary layer.
- A no-slip boundary condition is created as a result of the fluid and wall interaction (zero velocity at the wall).
- After that, the flow velocity above the surface steadily rises until it reaches the bulk flow velocity again.
- The term "velocity boundary layer" refers to the thin layer of fluid whose velocity has not yet recovered to that of the main flow.
The turbulent boundary layer has swirls or "eddies," whereas the laminar boundary has a fairly smooth flow.
- Laminar flow is less stable than turbulent flow but produces less skin friction drag.
- The area of a predominantly turbulent flow that is close to a no-slip boundary and where viscous shear stresses play a significant role is known as the laminar sublayer, also known as the viscous sublayer.

Answer:
You've already given the answer -- pseudo-listening -- so I'll just explain what it is.
Explanation:
Pseudo-listening refers to someone acting as if they are paying attention to what someone else is saying when, in reality, they are not. The other person believes you are listening because you act as if you are interested by maintaining eye-contact and nodding at intervals. The Greek root for pseudo means "not real" or "not genuine". Pseudo-listening is, in short, the action of pretending to listen to someone.
Answer:assimilation
Explanation: assimilation is a term used by Piaget to refer to how children associate new information with their pre-existing knowledge. So when they learn something new they try to relate it to what is already preserved in the pattern of knowledge in their mind. It this process thy don't change their schemas (pattern of information ) but they just relate it to what they already know . Accomodation is when they change the existing Information to fit in the new information.
There are four main types of unemployment in an economy—frictional, structural, cyclical, and seasonal—and each has a different cause. Frictional unemployment. Frictional unemployment is caused by temporary transitions in workers' lives, such as when a worker moves to a new city and has to find a new job.
