Answer:
Wet unit weight = 1.94 g/cc
Dry unit weight =1.05 g/cc
density of saturation = 0.41
porosity = 0.43
Explanation:
given data
Void ratio = 0.78
Water content -12%
Specific gravity of solids - 2.68
to find out
Wet unit weight and Dry unit weight and Degree of saturation and Porosity
solution
we know that Wet unit weight formula is
Wet unit weight = 
density of water
here Gs is specific gravity of soild and e is void ratio and density of water is 1
so Wet unit weight = 
Wet unit weight = 1.94 g/cc
and
Dry unit weight = 
density of water
Dry unit weight = 
Dry unit weight =1.05 g/cc
and
density of saturation is
density of saturation = Wc × 
her Wc is water content
so density of saturation = 0.12 × 
density of saturation = 0.41
and
porosity is
porosity = 
porosity = 
porosity = 0.43
Answer:
HDI classify between countries on the basis of their:
1- per capita income
2- literacy rate
3- net attendance ratio
4- life expectancy from birth
UNDP uses criterion of HDI is classify countries.
The further from the trench an earthquake's epicenter is, the deeper it is - assuming the earthquake is related to a plate being subducted.
<u>Explanation:</u>
The depressions that are very long and narrower and that exists on the seafloor refers to the Ocean trench. Theses are found on the deepest parts of the ocean. They encapsulate the regions that are prone of volcanic eruptions and also zones of earthquake.
The subductions that are caused in the plates are the ocean trench. These are formed due to the tectonic activity. These are caused mainly due to the movement of the lithosphere of Earth. The process of subduction that results in the trench formation that causes the lithosphere that has high density to move below the lithosphere of lower density.
