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.

Hi there,

The climate in Saudi Arabia, Iraq, and Iran is mainly Desert.

Those places are located around the Middle East area and the Middle East is covered in dry hot sand so it'll make sense that Saudi Arabia, Iraq and Iran is a desert.

Hope this helped :)

Have a great day
