Acceleration can be defined as the rate at which velocity is changes by an object.
<u>Explanation:</u>
Acceleration is a quantity of vectors which is characterized as the rate at which an entity shifts its velocity. An object accelerates when its velocity is shifting. The acceleration unit is meters per second squared. As velocity is a speed and a direction, two methods from which one can accelerate: change your speed or change your direction or change both.
If one don't change its pace and also donot change its direction then he or she simply won't be able to accelerate, no matter how quickly one go. Therefore, a jet traveling at a constant speed of 800 miles per hour along a single direction has zero acceleration, although the plane goes very fast, as the speed is not increasing.
I believe the answer is b. because The Know Nothing movement also briefly emerged as a major political party in the form of the American Party, and they were primarily an anti-Catholic, anti-immigration, and xenophobic movement, originally starting as a secret society. So they wouldn't be supported by Catholics if they were anti-Catholic, right?

Connecting the coasts made exportation easier to the Eastern markets. The development of the railroad also brought about new economic opportunities and new territories were also easily accessible.
