Answer:
specific weight = 49.7 lb/ft^3
specific gravity = 0.797
Explanation:
From Appendix A,
pk = 1.58 slug/ft^3
pea = 1.53 slug/ft^3
volume of kerosene is
Vk = 14 ft^3 - 10 ft^3 = 4 ft^3
The total weight of the mixture is therefore
W = pk g Vk + pea g Vea
= (1.58 slug/ft3) (32.2 ft/s^2) (4 ft^3) + (1.53 slug/ft^3) (32.2 ft/s^2) (10 ft^3)
= 696.16 lb
The specific weight and specific gravity of the mixture are
γm = W
/V
γm = 696.16 lb/ 14 ft^3 = 49.73 lb/ ft^3 = 49.7 lb/ft^3
Sm = γm / γv
Sm = 49.73 lb/ft^3/ 62.4 lb/ft^3 = 0.797
I agree with him I also think it is #2 but it's hard to explain, it just makes more sence...
hope this helps!
They will repeal(that is the correct answer to the question)<
A solution is a homogenous mixture of two or more substances. A solute is a substance that dissolves. A solvent is a substance in which other substances dissolve in. Using these definitions above the answer will hence be choice number 4. solvent;solute;solution.
Steel is an alloy, or a solution of several metallic elements. Although some steels can technically be heterogenous, steel is generally a homogenous mixture/solution.
