Answer:
probably b but not sure
Explanation:
The longitudinal modulus of elasticity of this material if the respective volume fractions of the aramid and glass fibers are 0.24 and 0.28, given the following data is 32.6 GPa.
What is elasticity?Elasticity is defined as after the forces producing the deformation are eliminated, a material body that has been distorted has the ability to revert to its original size and shape. Metals' atomic lattices undergo size and form changes when forces are applied. When forces are removed, the lattice returns to its initial, lower energy condition. Rubbers and other polymers are elastic because stretching of polymer chains occurs when forces are applied.
Longitudinal modulus are defined as the proportion of a material's length change caused by applied force to its initial length. Young's modulus is a measurement of a material's capacity to endure changes in length when subjected to compression or tension along its length.
Thus, the longitudinal modulus of elasticity of this material if the respective volume fractions of the aramid and glass fibers are 0.24 and 0.28, given the following data is 32.6 GPa.

Users of E85 see a drop in gas mileage because ethanol can't produce the same
amount of energy gasoline can. How much of a drop do they see?
Select one:
a. They see a 10-20% drop in gas mileage
b. The statement is wrong. There is no drop in gas mileage.
c. They see a 30-40% drop in gas mileage
d. They see a 20-30% drop in gas mileage
Answer:
A
Explanation:
Due to ethanol's lower energy content, FFVs operating on E85 get roughly 15% to 27% fewer miles per gallon than when operating on regular gasoline, depending on the ethanol content.
