To build a car that almost anyone could afford to buy
Solution :
The semi-major axis of any terrestrial body may be defined as equal to mean distance of the body, so that the cube of its mean distance of the planet is directly proportional to the square of the sidereal period.
It is given by Kepler's third law,

where p is the orbital period
a is the semi major axis
Given :
a =
m
Therefore, a =
m
= 3.3 AU
So, 

p = 6 years (approximately)
or p =
seconds ( since, 1 year =
seconds )
Answer:
Atlanta is a city that came into being because of the railways.
Explanation:
In 1837, the Western and Atlantic Railroad chose a spot close to the Chattahoochee River in Northern Georgia and decided it would be the end of a railway line to be built from Chattanooga, Tennessee. The town that evolved around this end of the line point was first called Terminus. The town's name was changed to Atlanta in 1845 and two other railway lines were established. This connected Atlanta to a diverse range of different areas of the country. This led to steady growth levels in the city as people tied to the railways and merchants and other businesses came to settle in the city.
