For the Indians to be gone so there are no more people of color
The 13th Amendment abolished slavery
The 14th Amendment states all people born or naturalized in the United States are citizens
The 15th Amendment gives everybody the right to vote no matter that citizen's race or color
All of these succeed because they allowed all African Americans to be free from slavery and granted them the right to citizenship. All Amendments are still enforced to this day and will never be removed from the Constitution.
We are given with:
Q = 700 J
W = 400
U1 = 1200 J
From the first law of thermodynamics
Q = ΔU + W
Q = U2 - U1 + W
U2 = Q - W + U1
U2 = 700 - 400 + 1200
U2 = 1500 J
We are given with
Q = 500 J
W = 300 J
U1 = 1500 J
U2 = 500 - 300 + 1500
U2 = 1700 J
<span>the answer is 1) 1500 J, 2) 1700 J </span>
