Answer:
The force F1 = 10 N when d1 = 4 m. The square of 4 m is d1² = 16 m². When d = 2 m, its square is d2² = 4 m². Solving for F2
F2× d2² = F1× d1²
F2 × 4m² = 10 N × 16 m²
F2 = (10 N × 16 m^2) / 4 m² F2
= 10 N× (16 m² /4 m²)
F2 = 10 N × 4
F2 = 40 N
The gravitational force produced when they are kept 2 meters apart is 40 N.

Answer: In the nineteenth century, England was able to use its already powerful merchant navy to sell the huge amounts of manufactured products made by the factories built as a result of the Industrial Revolution and the invention of steam-powered machines that enabled workers to work faster and yield a greater production than ever before. The economic power obtained through trade made it possible for England to conquer more countries where it could sell its products with no competition.
