Answer:
(A) Dry unit weight. = 15.71 kN/m³ =100.91 pcf
(B) Porosity = 40.82 %
(C) Degree of saturation = 66.52 %
(D) Weight of water, in pounds per cubic foot, to be added to reach full saturation = 81.22 pcf
Explanation:
(A) γd =
= 
KN/m³
(B) 
therefore 
1.69
Therefore e = 0.69 and
Porososity n = 
=
× 100% = 40.82 %
(C) 
therefore S =
= 
×100 = 66.52 %
(D) 
= 
= 19.68 kN/m³
The required amount of water is found from γ =ρ×g
ρ mass of water = 
1 kg/m³ = 0.062 pcf therefore 1301 kg/m³ = 1301 ×0.062 pcf or 81.22 pcf

Explanation:
Answer:
starburst
Explanation:
There are many different kinds of "hazard symbols," which are being used in order for people to recognize what kind of material they are handling. When it comes to "pictograms," the symbol for a hazard class of explosive is an exploding bomb that shows a<em> starburst effect.</em> An example of such chemical is the <em>"organic peroxide" </em>and other<u> self-reactive chemicals.</u>
A "flame" is a hazard symbol for<em> flammable substances</em>. A<em> </em>"gas cylinder" is a hazard symbol for <em>gases that are located in containers that are under pressure.</em> A "test tube" is a hazard symbol for <em>substances/materials that cause corrosion to skin.</em>
