Answer:
<em>The Answer to question 14 is : glycerol (n=1.47)</em>
Answer:
the sp³ orbital, is a very directional orbital that forms the bonds called covalent. the material is an electrical Insulator. hardness of the material comes from the energy needed to break the covalent bonds (sp³)
Explanation:
Carbon has several structures, for its different ways of bonding, in all these the orbital s is excited and mixed with the orbitals p, creating hybrid orbitals sp³, sp² and sp, there are some π orbitals around the latter.
Each type of hybrid orbital is linked differently, the sp³ orbital, is a very directional orbital that forms the bonds called covalent, where when it binds to another atom they share an electron, therefore the 4 sp³ orbitals form a stable molecule with full orbitals (8 electrons).
As the electrons are in the direction of the links, they cannot be easily moved, so the material is an electrical Insulator.
The hardness of the material comes from the energy needed to break the covalent bonds (sp³), there are only a few directions in which the links can be separated
current . . . flow of electric charges
voltage . . . stored potential energy at the source of a circuit
resistance . . . opposition to the flow of electric current

Answer:
given,
volume = 133.7 ft³
1 ft³ = 0.0283 m³
133.7 ft³ = 133.7 × 0.0283 = 3.784 m³
mass = 268 kg
1 kg = 2.204 lb
268 kg = 268 × 2.204 = 590.672 lb
weight of the fuel = 268 × 9.8 = 2626.4 N
1 N = 0.2248 lbf
2626.4 N = 2626.4 × 0.2248 = 590.414 lbf
ρ = 70.82 kg/m³
specific volume =
= 0.226 ft³/lbm
Net Force is Zero because both forces cancel each other out
