Answer:
You can take better notes by writing down the vocab word and the defination and highlight just the word. You can also take color coded notes that will help you become a better notetaker.
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.

Marxism theory is that the upper tear of society rules the lower tear, and institutions like social welfare is one way that the lower class tries prevent their exploitation. This is Social Control of the social classes. The lower tear engaging in welfare is the exorcize of their power,

The statement is TRUE.
In 1951 Solomon Asch carried out the famous Conformity Experiments, set out to <u>measure the dynamics of group-thinking</u>. He presented his subjects with an extremely simple judgement task with a very obvious answer, joined by a previously prepared group that was told to answer incorrectly on purpose. By making it so simple, it would be clear that any subject that answered incorrectly would be doing it because of group pressure. With this first experiment, <u>Asch proved a correlation between a group's influence on an individual's conformity</u>.
Further trials went deeper into which factors were the most impactful to influence conformity. The results showed that <u>increasing group size</u> by up to three times, <u>raised the conformity levels to 32%</u>. However, larger groups did not impact this number. Applying group unanimity, on the other hand, showed an increase of as much as 80% on the conformity rates.
This clarified how much bigger of an influence unanimity was over group size, meaning it mattered more to an individual if an entire group agreed on something (even if the group was small), over a larger majority's opinion when a group was more split-up.
Hope this helps!
