Answer:
The presence of strong magnetic fields results in the slow convection and also prevents the movement of hot plasma from entering the region
Explanation:
The photosphere refers to the visible surface of the sun, whereas the sunspots are the small dark spots that occur on the surface of the sun. These sunspots are comparatively cooler than the other gases that are present in the photosphere. It is because of the presence of the strong magnetic field, that lowers the surface temperature and reduces the effects of convection process and does not allow the movement of hot plasma into the region.
Due to this obstruction in the release of heat in the sun's surface, the sunspots are cooler than the surrounding gases.
Answer:
Alaska and Louisiana.
Explanation:
Counties are a type of internal territorial subdivision in the United States, with a lower hierarchy than states. Thus, a set of several counties in turn forms a state. They are, in short, the form of local territorial organization of a specific and determined area, in turn made up of several cities.
The name "County" is used in the vast majority of the 50 states, except for two particular cases: Alaska and Louisiana. Thus, in Alaska these types of organizational structures are called "Boroughs", while in Louisiana their name is "Parishes", thanks to its French colonial heritage.
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
∴
