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.
Answer:
I Believe the answer is A
due to B being suggesting a solution, C testing for something, D he or she predicting things and
A sounds the most reasonable choice because "I am missing the ball most likely because I'm not keeping my eye on it." just matches the sentence it is a problem and could later maybe if rephrased be a question as well.
Answer:
The 'Middle Ages' are called this because it is the time between the fall of Imperial Rome and the beginning of the Early modern Europe. ... The Dark Ages are given this name because Europe was in disarray in comparison to the orderliness of classical antiquity and life was short and poor.
Contour lines determine the steepness of the land by how close they are together. Generally, contour lines rise to a particular scale (e.g. a line for every ten metres), therefore, if the contour lines are closer together then the height of that particular area has risen more steeply than if the contour lines are further apart where the steepness has increased more gradually.
Answer:
B) Singapore and Hong Kong
Explanation:
In Euromoneymagazine's 2017 semi-annual "Country Risk Rating. Singapore and Hong Kong was found to be the countries with the lowest political risk. This was as a result of stability in government which reduces the risk that their government would default on its financial commitments. And no possible changes in the business environment that may negatively affect operating profits.
