Answer:
To calculate the anomalies, from each monthly data point you subtract that month’s average. These monthly averages, called the “climatology”, are shown in the top row of Figure 2.
Answer: at the equator the normal force will be 3.4N less and at the North Pole = 980N
Explanation:
So, we will start the Calculation by considering the equation below;
Fnet = F(g) - F(N); where Fnet = mv^2/ r.
Hence, F(g) - F(N) = mv^2/ r -------------(1).
Making F(N) the subject of the formula, we have;
F(N) = Gm1m2/r^2 - mv^2/r.
Thus, we have;
Gm1m2/r^2 = 6.68 × 10^-11 × (5.98 × 20^24) × 100/ 6.38 × 10^6 = 980N.
Also, we have;
mv^2/r = m4π^2r/T^2.
100 × 6.38 ×10^6 × 4π^2/(24 × 3600)^2 = 3.4N
Therefore, at the equator the normal force will be 3.4N less and at the North Pole = 980N.
Explanation:
The Earth is comprised of many plates that float on the hot magma in the mantle layer. They are constantly moving but its so slow we can't feel it. A long time ago, all the land on Earth was connected in one big continent named Pangaea. As the plates have moved the land has separated forming the continents.
When plates come together they cause friction between them. This causes the plates to push up forming a mountain. This was how the Himalayan mountains were formed.
Answer:
B. Geocentric solar system
Explanation:
The scientific community is the one that accepts or dismisses theories. Some theories are accepted, and that is because there are enough evidence that support them, while some theories are dismissed as they have been proven over time that they are not correct.
One of the theories that is outdated and has been dismissed by the scientific community is the theory of the geocentric solar system. This theory has been in place and widely accepted for a very long time, pretty much two millenniums.
This theory was basically suggesting that the Earth is the center of the solar system. The Sun, Moon, all the other planets that were known, as well as the stars, were all orbiting around the Earth. This has been proven as wrong (except that the Moon is orbiting around Earth), and that the theory is far away from the truth, so naturally once there were enough evidence it was dismissed.
