Since the U.S. was fighting against communist nations in WW ll, I'd say answer A.
That was when the U.S. first realized how dangerous communism is, since the whole nation in a sense follows the wants of one man.
Fighting against Hitler, Mussolini, and the other guy (I can't remember who it was) really opened America's eyes to the horrors of communism, which is why they decided to strengthen the Democratic side of America.
I believe answer A. is correct.
Answer:
In the United States, voting poll taxes (whose payment was a precondition to voting in an election) have been used to disenfranchise impoverished and minority voters (especially under Reconstruction).
Answer:
My Take on this
The height of the wall can be related with the Horizontal distance traveled by the equation of the trajectory
y=xtan∆ - gx²(1+tan²∆)/(2u²)
The wall is at distance x1
So thats the horizontal distance we'll use... We need to find its corresponding vertical distance "y"
So
Applying the formula
∆=45°
x=x1
g=9.8ms-²
u=velocity of projection
Substituting
y= x1tan45 - 9.8x1²[1+(tan²45)]/2u²
tan45°=1
y= x1 -4.9x²(1 +1)/u
y= x1 - 4.9x²•2/u²
y= x1 - 9.8x²/u².
