An aircraft component is fabricated from an aluminum alloy that has a plane strain fracture toughness of 40 . For an applied str
erma4kov [3.2K]

Answer:

B. 2.3mm

Explanation:

The correct answer for the given question is B. 2.3mm. Some aircraft are made are fabricated from aluminium which has plane stain fracture toughness. In the given scenario the plane stain toughness is

Ktc = 40 [ MPa \sqrt{(m)} ]

When the Ktc increases the fracture will appear on the aircraft. In this case the maximum crack until the fracture failure is 2.5mm.

When considering free energy change, biochemists usually define a standard state, the biochemical standard state, which is modif
Softa [21]

Answer:

Maximum work under this condition (∆G) = Maximum work under Standard Condition (∆G°) + Activities defining this condition

Explanation:

In this equation, the term DGo provides us with a value for the maximal work we could obtain from the reaction starting with all reactants and products in their standard states, and going to equilibrium. The term DG' provides us with a value for the maximal work we could obtain under the conditions defined by the activities in the logarithmic term. The logarithmic term can be seen as modifying the value under standard conditions to account for the actual conditions. In describing the work available in metabolic processes, we are concerned with the actual conditions in the reaction medium (whether that is a test-tube, or the cell cytoplasm); the important term is therefore DG'. If we measure the actual activities (in practice, we make do with concentrations), and look up a value for DGo in a reference book, we can calculate DG' from the above equation.

Values for DGo provide a useful indication through which we can compare the relative work potential from different processes, because they refer to a standard set of conditions.

Therefore both phrases describe the Biochemical and Chemical Standard State

Polymers can be natural or synthetic. a)-True b)- false?
Olenka [21]

Answer:

TRUE

Explanation:

Polymers can be natural as well as synthetic

The polymer which are found in nature are called natural polymer tease polymer are not synthesized, they are found in nature

Example of natural polymers is cellulose, proteins etc

On the other hand synthetic polymers are not found in nature they are synthesized in market

There are many example of synthetic polymer

Example : nylon, Teflon etc  

So it is a true statement

stellarik [79]

Answer:

1 2 200 000 000 000 000 000 000 (20 zeros) molecules

Explanation:

Molar mass of 1-butanol = 74.121 g/mol

number of moles = mass given / molar mass

where mass given = 1.5 g

number of mole = 1.5 g / (74.121g/mol ) = 0.0202 moles

number of moles = number of molecules / Avogadro's constant

where Avogadro's = 6.022 × 10²³ mol⁻¹

number of moles = 6.022 × 10²³ × 0.0202 moles = 1 2 200 000 000 000 000 000 000 (20 zeros) molecules
