Answer: A)
Explanation:
A space enclosed within two sets of double solid yellow lines is off-limits and exists as a buffer zone to keep cars apart.
Two sets of double lines that are yellow are indicating those cars who are on the road and they are changing tracks restricted so the answer A is correct and these lines can keep cars apart in a buffer zone.
A democracy is a system in which the people vote and everyone is equal (ideally). In practice, in most if not all democracies (especially in America), some group or groups are disadvantaged in some way, be it voting rights, judicial rights, social rights, etc. This widespread inequality has led to the concept of <span>democratic ideals. </span><span>It has nothing to do with the Democratic Party, it is just mostly associated with that because the Democratic Party is trying to move further to the left and be more socially liberal to combat the Republican Party becoming more socially conservative. While there are disadvantaged groups in America (gays, trans people, Muslims, African-Americans, and the mentally/physically disabled to name a few), there will always be the </span><span>democratic ideals </span><span>there to combat that discrimination. The political parties of America are no longer about the economy. They are almost solely dedicated to the social issues in the United States and abroad.</span>

is a shared drive among members to succeed and work interdependently to achieve
their final goal. They recognize each member’s part in accomplishing a task. The
term is usually linked to an increase in productivity and effectiveness. </span>
The thickness up to which the velocity approaches 99% of the free stream velocity. The distance measured perpendicular to the boundary by which the free stream is displaced on account of the formation of the boundary layer.
<h3>What is displacement thickness in boundary layer theory?</h3>
The displacement thickness for the boundary layer is defined as the distance the surface would have to move in the y-direction to reduce the flow passing by a volume equivalent to the real effect of the boundary layer.
The thickness of the boundary layer represented by δ is arbitrarily defined as that distance from the boundary surface in which the velocity reaches 99% of the velocity of the mainstream.
