Position papers are published in academia, in politics, in law and other domains. The goal of a position paper is to convince the audience that the opinion presented ...
Streamline position is the basis of the spinal axis strokes, backstroke and freestyle, as well. A swimmer will try to maintain a straight back and legs to minimize 'drag' during the stroke. The Fédération Internationale de Natation (F.I.N.A.), otherwise known as the International Swimming Federation , has strict rules on how and when ...
The face-down swimming position allows for a good range of motion of the arm in the water, as compared to the backstroke, where the hands cannot be moved easily along the back of the spine. The above-water recovery of the stroke reduces drag, compared to the underwater recovery of breaststroke .
This is because when a particle on a streamline reaches a point, , further on that streamline the equations governing the flow will send it in a certain direction . As the equations that govern the flow remain the same when another particle reaches a 0 {\displaystyle a_{0}} it will also go in the direction x → {\displaystyle {\vec {x}}} .
A Stellantis joint venture with Samsung SDI has won a commitment from the U.S. government for up to a $7.54 billion loan to help build two electric vehicle battery plants in Kokomo, Indiana. The ...

Although a common classroom experiment is often explained this way, [438] Bernoulli's principle only applies within a flow field, and the air above and below the paper is in different flow fields. [439] The paper rises because the air follows the curve of the paper and a curved streamline will develop pressure differences perpendicular to the ...
