The correct answer would be B. The first level contains two and the second level contains six holding a total of eight, the reason eight aren't just in one row is because only two fit in the first row.
Answer:
Explanation:
From the question we are told that
The hydraulic conductivity is 
The effective matrix potential 
The intensity of rainfall is 
The runoff rate 
Generally the run off rate is mathematically represented as
Here t is the amount of runoff generated
=> 
=> 
converting to minutes
Answer:
<em>10.09 units</em>
Explanation:
For the A
Ax = -8.0 units
Ay = 6.0 units
The resultant vector = Ra = 
Ra = 
= 10 units
For B
Bx = 1.0 units
By = -1.0 units
The resultant vector = Rb = 
Rb = 
= 
units
Adding these two vectors A and B together, magnitude of vector R is
R = 
R = 
= <em>10.09 units</em>
Land: Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills. Erosion by water and wind can wear down land and create landforms like valleys and canyons. ... Landforms can exist under water in the form of mountain ranges and basins under the sea.
Atmosphere: (4.6 billion years ago)
As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today's atmosphere. After about half a billion years, Earth's surface cooled and solidified enough for water to collect on it.
Ocean: After the Earth's surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries. As the water drained into the great hollows in the Earth's surface, the primeval ocean came into existence. The forces of gravity prevented the water from leaving the planet.
