Answer: Annexation, war, expansion, shopping.
Explanation:
These are the essential elements of United States expansion. For this purpose, the United States annexed Texas. In 1803 the united states purchased from Lusiana from the French. In 1819, Spain thus surrendered the United States to Florida, and later, on the western borders of the continental United States, New Spain was replaced by independent Mexico. The famine for the new land was the cause of increasing conflict with Native American tribes, as well as the violent expulsion of Native Americans to areas west of the Mississippi River in 1830. Part of the American colonists also began to settle in the area under simple Mexican rule, including the city of present-day Texas. 
In 1836, the settlers there started an insurgency against Mexico, and after a brief war, declared the independent Republic of Texas. In the case of Mexico, the accession of Texas to the United States led to the American-Mexican War (1846-1847). US forces defeated Mexico and forced it to hand over 42% of its territory, including California, to the Guadelupe Hidalgo Peace Treaty. On October 18, 1867, America bought Alaska from Russia and thus occupied this part of the country.
 
        
             
        
        
        
Answer:
5.71 x 10^13 C.
Explanation:
We are given the following parameters or data or information and these data are going to help us in solving this particular Question or problem effectively and efficiently; 
=> mass of Earth = 5.98 × 10^ 24kg, mass of Moon = 7.35 × 10^22 kg and the radius of orbit = 3.84 × 10^8m.
Recall that H =( G × m1 × m2) / r^2. where m1 and m2 are the masses of the two bodies amd r is the radius.
We will be making use of the formula below: 
 the value of Q to maintain the present orbit = √ { ( 7.35 × 10^22 ) × (5.98 × 10^24) × 4 × π × V. 
the value of Q to maintain the present orbit = 5.71 x 10^13 C.
 
        
             
        
        
        
The first Gasoline powered American automobile was made in: The late 1800s
The first Gasoline car was created by a company called Duryea Motor Wagon in Massachusetts. At that time, only an extremely wealthy people can afford it and the product is not really appealing among the mass since horse Caravan was still a much faster transportation at that time.
