It was the federal companies that built some of the first road of the nation.
Explanation:
Route 40 or the transnational road came into existence in 1811 as Jefferson and Washington had envisioned for modern roads to connect the whole nation.
This project was done over the next two decades.
These roads were not like the roads we have now whoever.
Those roads which are pave roads of concrete came into existence in 1909 and were mostly built by private companies in this century.
Even now only 70 percent of the roads in US are paved because of the rugged terrains in large parts of the country.
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.
