You might mean a boundary.
Sometimes it doesn't.
It only happens in the summer and it's because Alaska is closer to the North Pole. At the North Pole the Sun never sets - but only between March 21 and September 22.
The velocity at a stationary boundary is zero because the boundary is not moving, thus preventing the fluid from moving past it. This creates a no-slip condition where the fluid particles in direct contact with the boundary stick to it and do not move. This stagnant layer of fluid at the boundary sets the velocity at zero.

Relevant range is an accounting term that pertains to the minimum and maximum value. It sets the cost boundary in a certain activity level.
Lectures of college algebra about sets could include: * Describing sets * Relationship between sets * Basic operation in sets * Solving problems using Venn diagram
When two sets do not have any elements common between them,they are said to be disjoint.
