Answer:
[tex]\mathbf{Q_p =682 \ \ ft^3/s}[/tex]
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 [tex]t_c = 0.0078L^{0.77} S^{-0.385}[/tex]
where;
L = 6870
S = 5/264
[tex]t_c = 0.0078(6870)^{0.77} (\dfrac{5}{264})^{-0.385}[/tex]
[tex]t_c =32.34[/tex] min
Since 60 min = 1 hour
32.34 min will be (32.34*1)/60
= 0.539 hour
Lag time [tex]T_l = 0.67\times t_c[/tex]
[tex]T_l = 0.67\times 32.34[/tex]
[tex]T_l = 21.6678\ min[/tex]
The time to peak i.e
[tex]T_p = \dfrac{D}{2}+ T_L \\ \\ T_p = \dfrac{15}{2}+ 21.6678 \\ \\ T_p = 29.168 \ min[/tex]
[tex]T_r = \dfrac{T_p}{5.5} \\ \\ T_r = \dfrac{29.1678}{5.5} \\ \\ T_r = 5.30 \ min[/tex]
Since D = 15 min is not equal to [tex]T_r[/tex], then we hydrograph apart from [tex]T_r[/tex] duration lag time.
Then;
[tex]T_p \ ' = T_p + \dfrac{D-t_r}{4} \\ \\ T_p \ ' = 29.168 + \dfrac{15-5.30}{4} \\ \\ T_p \ ' = 31.593[/tex]
Now, we need to determine the peak discharge [tex]Q_p[/tex] by using the formula:
[tex]Q_p = \dfrac{484 \times A}{T_p \ '}[/tex]
where
484 = peak factor
Recall that A = 475 acres, to miles, we have:
A = 0.7422 mile²
[tex]T_p \ ' = 31.593/60[/tex]
∴
[tex]Q_p = \dfrac{484 \times 0.7422}{\dfrac{31.593}{60}}[/tex]
[tex]\mathbf{Q_p =682 \ \ ft^3/s}[/tex]

The correct answer is D. Assigning representatives to control different provinces.
Explanation
Chandragupta Maurya was a Maurya leader who managed to unify much of the territory of the Indian subcontinent. During his mandate, he defeated several Greek armies motivated by the conquest of new territories in Asia. In addition, he meant an improvement in economic activities, internal and external trade, and agriculture. In the administrative aspect, he stood out for delegating governance responsibilities to representatives who controlled different provinces to provide security to the population because the size of the Empire's territory prevented him from governing from a center of power, so he had to delegate powers to avoid weakness throughout the territory. Therefore, the correct answer is D. Assigning representatives to control different provinces.
What kind of landform is found in
a divergent boundary at the
bottom of the ocean?
Answer:
Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.

A stone dropped freely from 72m height of
the tower and reaches the "ground on 6 seconds
calculate acceleration due to gravity of that stone
At what condition does the acceleration due to
gravity becomes Zero
When the initial velcity is 12 m/sec in that condition the acceleration due to gravity becomes Zero.
What is acceleration?The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
The height from the stone drop,h= 72 m
t is the time period=6 sec
From Newton's second equation of motion;
[tex]\rm h = ut +\frac{1}{2} gt^2\\\\[/tex]
The condition does the acceleration due to gravity becomes Zero will be;
The gravitational acceleration is zero;
[tex]\rm h = ut +\frac{1}{2} \times 0t^2\\\\h=ut \\\\ 72 =6u \\\\ u= 12 m/sec[/tex]
Hence when the initial velcity is 12 m/sec in that condition the acceleration due to gravity becomes Zero.

ОВ Oil production has increased Indigenous people are more likely to be poor . Oc Economic growth has improved Fewer children are attending school. O Few citizens have access to education. Most countries in the region remain poor.
The diagram best representing an economic problem facing Pacific South America would be that economic growth has improved, but fewer children are attending school. This is best represented by option C.
The diagram presented by option C highlights that the economic growth doesn’t all go into educational opportunities for everyone. While the economy grows, the constant decline in school attendance shows that the economy is faced with a problem of providing access to education for the younger developing populations.

despite of many benefits, aquaculture is actually not considered a sustainable activity in the perception of the scientific community and the average population. why aquaculture is considered nonsustainable activity?
Answer:
Aquaculture has been considered as an option to cope with the world food demand. However, criticisms have arisen around aquaculture, most of them related to the destruction of ecosystems such as mangrove forest to construct aquaculture farms, as well as the environmental impacts of the effluents on the receiving ecosystems. The inherent benefits of aquaculture such as massive food production and economical profits have led the scientific community to seek for diverse strategies to minimize the negative impacts, rather than just prohibiting the activity. Aquaculture is a possible panacea, but at present is also responsible for diverse problems related with the environmental health; however the new strategies proposed during the last decade have proven that it is possible to achieve a sustainable aquaculture, but such strategies should be supported and proclaimed by the different federal environmental agencies from all countries. Additionally there is an urgent need to improve legislation and regulation for aquaculture. Only under such scenario, aquaculture will be a sustainable practice.

In 2010, the Soufriere Hills volcano on the Caribbean island of Montserrat erupted violently, spewing huge clouds of ash and gases into the sky. How do the volcanic eruptions at the end of the Permian period and the formation of Pangaea, both of which occurred about 252 million years ago, set in motion events that altered evolutionary history
Answer and Explanation:
Pangaea is the term used to describe the supercontinent that existed millions of years ago, before the continents were spread across the globe as we know it today. The separation of continents occurs due to the rapid convections of the Earth's mantle. These mantle convections increased volcanic activity on the earth, making volcanism very active and causing numerous volcanic eruptions, which increased the concentration of carbon dioxide in the atmosphere, increasing the greenhouse effect and creating a long period of intense global warming.
It was this global warming that altered the evolutionary events on earth, promoting a strong natural selection of plants and animals, which even led to the creation of new species and extinction of old species, in addition to creating a geographical and environmental modification.
La Soufriere Hills volcano is a group of active volcanoes. The volcanic eruptions altered the climatic conditions and led to natural selection.
What is Pangaea?Pangaea was used to describe the supercontinent that existed millions of years ago before the separation of the continents present now. The rapid convections in the mantle of the Earth caused the shift and drift in the tectonic plates.
The movement of the tectonic resulted in increased volcanic activities that caused numerous volcanic outbreaks resulting in increased carbon dioxide concentration in the environment.
This led to global warming and resulted in a change in climatic conditions. Global warming altered the evolution of the organisms through the process of natural selection and led to the extinction and the introduction of species.
Therefore, volcanic eruptions and Pangaea resulted in environmental and geographical alterations.
