Answer:
A-The Amazon acts as more of a barrier to movement
b- The Amazon is much harder to get to
c- The Amazon is surrounded by farmlands
Explanation:
The Amazon river has surroundings which are largely underdeveloped with large amount of plant life. They also inhabit lots of animal life too.The surroundings are hard to get to due to poor road network.
The Mississippi River however is found in a more developed industrial area and lacks a dense plant population with good road networks.
Fossils help scientists date rocks: True
Sometimes younger rock layers are found beneath older rock layers: True, because it happens with landslides and other causes.
No fossils from the Precambrian era have been found because there were no organisms at the time: False because there were organisims like algae and bacteria, and there are a very small amout of fossils from that era.
The map of Earth has changed over millions of years, but is now set: False
The free body diagram consists of:
1) Weight force, which is a vertical arrow downward
2) A Normal force that is perpendicular to the ramp.
The Normal force can be decomposed in a vertical component and an horizontal component.
The vertical component, Ny, must equal the weight force, due to equilibrium (rest) condiition =>
Ny = weight = m*g = 5.5kg*9.8m/s^2 = 53.9 N
By geometry the vertical component of the Normal force, Ny is such that
cos (angle) = N / Ny => N = Ny * cos(angle)
=> N = 53.9N * cos(angle)
Now use that equation for each option:
a) 0 ° => N = 53.9N * cos(0) = 53.9N
b) 12° => N = 53.9 * cos(12) = 52.7N
c) 25° => N = 53.9 * cos(25) = 48.9N
d) 45° => N = 53.9 * cos(45) = 38.1N
Answer:Through relocation diffusion, Christianity first diffused from its hearth.
Explanation: Christianity originated from Judea, in the Roman Empire. When people soon moved out, the people who believed in this religion shared it to others around them. This shows relocation diffusion, “ The spread of an idea through physical movement of people from one place to another.”
