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

∴


At the bottom of the food chain, green phytoplankton is eaten by krill and shrimp. The krill and shrimp are later eaten by squid, whales, and fish. Later, seals, penguins and birds eat the squid. Finally, killer whales/orca eat squid as well.

Answer:
English in the U.S, Hindi in India, Bengali in Bangladesh, and Punjabi in Pakistan are all total different languages. I myself only know 3 Korean, English and Chinese. For example imagine I didn't know English and only Korean and traveled to the USA. It would be really hard to ask for something because I wouldn't know the language! So that is how language acts as a centripetal force.
Explanation:
The correct answer among the choices presented above is the fourth option. Magnetic minerals are a part of molten rock at mid-ocean ridges. Examples are chromite, magnetite, limenite and ferberite. Hope this answers the question.
Answer:
on land but close to oceans
Explanation:
A boundary between an oceanic plate and a continental plate will be near a coastline., not "far from the coast" or "in the middle of oceans."
Often, mountains are also near that boundary, but mountains may also exist elsewhere, so "anywhere there are mountains" is not an apt description.
The best choice is "on land but close to oceans."

The 2011 Tohoku earthquake near Japan was offshore by 67 km. It came from the subduction zone where the Pacific plate dives beneath the Eurasian plate. It is an example of a plate boundary quake that occurred offshore, rather than on land.
