Answer:
The event is known as the Trail of Tears
Explanation:
In 1830, congress passed the Indian Removal Act. This law allowed then-president Andrew Jackson to remove the native indian populations of the Southeastern United States, to a new territory in Oklahoma, known as the Indian Territory.
Over 30thousand people belonging to the tribes mentioned in the question were obliged to abandon their homelands, and move westward. During this event, a lot of them died of diseases and starvation. This sad reality is the reason why it has come to be known as the Trail of Tears.
Answer:
Explanation:
Given that:
Area = 475 acres
The length of the channel (L) = 6870 feet
The average water shield slope (S) = 100 feet/mile
Since; 1 mile = 5280 feet
Burst duration D = 15 min
∴
100 feet/mile = 100/5280
The average water shield slope (S) = 5/264
Using hydrograph method:
The time of concentration 
where;
L = 6870
S = 5/264
min
Since 60 min = 1 hour
32.34 min will be (32.34*1)/60
= 0.539 hour
Lag time 
The time to peak i.e
Since D = 15 min is not equal to 
, then we hydrograph apart from duration lag time.
Then;
Now, we need to determine the peak discharge 
by using the formula:
where
484 = peak factor
Recall that A = 475 acres, to miles, we have:
A = 0.7422 mile²
∴
Meteorology is the study of Earth's atmosphere and its changing conditions. Under this study includes the different changing weather conditions, its temperature and moisture patterns. Typhoons, tornadoes, snow hail, etc are being studied here. Meteorology because more or less meteors and atmosphere patterns are quietly related.
