The Milky Way. Hope this helps
Your correct answer is B, a mercator map. the Mercator projection, the map most commonly seen hanging in classrooms and in text books, was created in 1596 to help sailors navigate the world. The familiar map gives the right shapes of land masses, but at the cost of distorting their sizes in favour of the wealthy lands to the north.<span>

Answer:
One solar eclipse and one lunar eclipse each month
Explanation:
Solar eclipse are due to the moon in front of the sun before the earth, while lunar eclipse while lunar results when earth cast it shadow on a full moon.
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.
