Answer:
the activity or condition of competion
Answer: hello your question is in complete below is the complete question
A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPA, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl = ViEi + EmVm? (note Vi + Vm= 1.) O 5.88 GPa O 5.66 GPa O 2.52 GPa O 6.74 GPa
answer : 5.88 GPa
Explanation:
Fiber reinforced composite containing e-glass fibers
E for the glass ( Ei ) = 72 GPa
E for the epoxy ( Em ) = 2.4 GPa
<u>Determine the Elastic modulus of a composite containing 5% fibers </u>
percentage of glass = 5% = Vi = 0.05
∴ percentage of epoxy = 95% ; Vm = 0.95
using the relation included in the question
Ecl = Ei Vi + Em Vm
= ( 72 * 0.05 ) + ( 2.4 * 0.95 )
= 3.6 + 2.28 = 5.88 GPa
Answer:
Nucleic Acids
Explanation:
Between carbohydrates, lipids, proteins, and nucleic acids, DNA and RNA molecules most accurately fall under the macromolecular category of nucleic acids.
The Law of Superposition.
The Law of Superposition states that each layer is younger than the one beneath it.
Answer:
<em>Geographic isolation</em>
Explanation:
Geographic isolation can be described as a term that describes the model of speciation in which a biological population becomes isolated from other members of the population and can no longer have gene flow with them.
The same scenario of gene isolation is occurring in the species of taods which live at the top of the mountains in southern Arizona. This population has become reproductively isolated fro all other species of toads within the mountain range.
