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.
The ways to reduce the human impact on the environment is through the use of:
- Public transport
- A cycle or walk and not use a car.
- The use facilities and trips that are run by local people when possible.
- Do not destroy wildlife and disturb habitats.
<h3>What could be the actions that we can do to eliminate reduce this environmental problem?</h3>
Actions that a person can be take every day to lower one's ecological footprint or the mark a person leave on their natural environmental and its resources are:
- Instead of using disposal items, do use reusable items.
- The use of paper should be stopped .
- Keep water and electricity.
- Aid environmental friendly practices.
- Recycle waste.
Therefore, The ways to reduce the human impact on the environment is through the use of:
- Public transport
- A cycle or walk and not use a car.
- The use facilities and trips that are run by local people when possible.
