As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today's atmosphere.
Jackson.
Jackson encouraged Congress to adopt the Removal Act of 1830. The Act established a process whereby the President could grant land west of the Mississippi River to Indian tribes that agreed to give up their homelands.
Answer:
What sentence?
Explanation:
There is nothing below the question that I can see.
The Constitution doesn't belong to a bunch of judges; it belongs to the people: True.
<h3>What is a Constitution?</h3>
A Constitution is a set of formally written laws and principles which typically determines the power and authority of a democratic government, as well as guarantee the fundamental rights and freedom of her people (citizens).
In this context, we can infer and logically deduce that "The Constitution doesn't belong to a bunch of judges; it belongs to the people" as proclaimed by the United States of America Supreme Court Justice Anthony Kennedy.

Answer:
A) Cm = 2.232 s/mm²
B) Time taken to solidify = 74.3 seconds
Explanation:
(A) Since a side is 50mm and all sides of a cube are equal, thus, Volume of the cube is;V = 50 x 50 x 50 = 125,000 mm³
There are 6 faces of the cube, thus Surface Area A = 6 x (50 x 50) = 15,000 mm²
So, Volume/Area = (V/A) = 125,000/15,000 = 8.333 mm
Cm is given by the formula; Cm =[Tts] /(V/A)² where Tts is time taken to solidify and it's 155 seconds in the question. Thus;
Cm = 155/(8.333)²= 2.232 s/mm²
(B) For;Cylindrical casting with D = 30 mm and L = 50 mm.;
Volume of cylinder is;
V = (πD²L) /4
So,V = (π x 30² x 50)/4 = 35,343mm³
Surface area of cylinder is;
A = (2πD²)/4 + (πDL)
Thus, A = ((π x 30²)/2) + (π x 30 x 50) = 6126 mm²
Volume/Area is;
V/A = 35,343/6126 = 5.77 mm
Same alloy and mold type was hsed as in a above, thus, Cm is still 2.232 s/mm²
Since Cm =[Tts] /(V/A)²
Making Tts the subject, we have;
Tts =Cm x (V/A)²
Tts = 2.232 x (5.77)² = 74.3 seconds
