This city is the capital of the state of Georgia since 1868 and was burned during the Civil War.

Sphinxa [80]

The correct answer is - Atlanta.

Georgia is a state that has had multiple capitals since the arrival of the first European settlers, changing them very often in accordance to the circumstances. The last one in the row has been Atlanta. This city got the privilege to be the capital of Georgia in 1868 after the Atlanta council applied for it. The US government took everything in perspective, from infrastructure, population, location, and very importantly politics. The political aspect seems to be the case where Atlanta won the case to become capital, as the capital until than, Milledgeville, was still a city where the black population was not welcomed and the racism was still on a very high level.

Consider the medium of air as defined by the use of radio frequency. What made some of the early standards so slow compared to t

Tanzania [10]

Answer:

Explanation:

Earliest standards were dependent on a single frequency/channel to both send and receive. This shared medium creates the same problem as half-duplex coax cable. Because receivers had to wait for the signal before sending a response, this reduced the overall bandwidth.

Other factors affect wireless signal propagation, too, including RF interference, antenna choice, and obstacles such as walls, trees, and even weather (precipitation, for example).

When you exert 75 N on a jack to lift a 6000 N car, what is the jack’s actual mechanical advantage? Show your work.

professor190 [17]

Answer:

Explanation:

the mechanical advantage is the ratio of the load to the effort so it doesn't have units.to calculate it you use the formula

mechanical advantage=load/effort

in this case the load is 6000N and the effort is 75N

Ma=6000/75

=80

I hope this helps
