Answer:
The luminous intensity of the sun of the sun will vary from day to day depending on the amount of cloud cover in the sky. The more the clouds the less the luminous intensity of the sun, the less the clouds the more the luminous intensity of the sun on the earth.
Explanation:
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

∴


Answer:
The red lines on this map show us divergent plate boundaries.
Explanation:
The tectonic plates are in constant movement, and this results in interactions between them. At some places the plates collide, at other places slide past each other, and at some move away from each other. The last ones are the places where there is a divergent plate boundary.
The divergent plate boundaries can occur in the ocean or on land. When they occur in the ocean, they form an underwater mountain range, known as a mid-ocean ridge, which is volcanically highly active. An example of this is the mid-Atlantic ocean ridge. When these boundaries occur on land, they form rifts, where the crust starts to crack, a gap opens up, and gradually widens. An example of this is the Great Rift Valley of Africa.
