Answer:
The differences between the Lincoln, Johnson, and Congress Reconstruction plans include: Although both the Lincoln and Johnson plan were open to readmission of the southern States, Congress claimed that the two administrations were too lenient and sought stiffer punishment for the States
The aspect of Abraham Lincoln's plan for reconstruction in the South that made it differ from the plan of congressional leaders was that Lincoln's plan was more focused on helping the South rebuild than on punishing it and the Radical Republicans' reconstruction offered all kinds of new opportunities to African Americans, including the vote (for males), property ownership, education, legal rights, and even the possibility of holding political office. By the beginning of 1868, about 700,000 African Americans were registered voters.
Reconstruction encompassed three major initiatives:
1. restoration of the Union
2. transformation of southern society
3.enactment of progressive legislation favoring the rights of freed slaves
Answer:
vi = 4.77 ft/s
Explanation:
Given:
- The radius of the surface R = 1.45 ft
- The Angle at which the the sphere leaves
- Initial velocity vi
- Final velocity vf
Find:
Determine the sphere's initial speed.
Solution:
- Newton's second law of motion in centripetal direction is given as:
m*g*cos(θ) - N = m*v^2 / R
Where, m: mass of sphere
g: Gravitational Acceleration
θ: Angle with the vertical
N: Normal contact force.
- The sphere leaves surface at θ = 34°. The Normal contact is N = 0. Then we have:
m*g*cos(θ) - 0 = m*vf^2 / R
g*cos(θ) = vf^2 / R
vf^2 = R*g*cos(θ)
vf^2 = 1.45*32.2*cos(34)
vf^2 = 38.708 ft/s
- Using conservation of energy for initial release point and point where sphere leaves cylinder:
ΔK.E = ΔP.E
0.5*m* ( vf^2 - vi^2 ) = m*g*(R - R*cos(θ))
( vf^2 - vi^2 ) = 2*g*R*( 1 - cos(θ))
vi^2 = vf^2 - 2*g*R*( 1 - cos(θ))
vi^2 = 38.708 - 2*32.2*1.45*(1-cos(34))
vi^2 = 22.744
vi = 4.77 ft/s
It’s e 2.0 x 10^-4 because it is a fraction

Answer:
The astronomical model created and published by Nicholas Copernicus in the year 1543 is called Copernican heliocentrism. The model set the Sun in immobile position near the center of the solar system with Earth, as well as the other planets, spherical, epicycled and at consistent frequencies around it.
