Option C

A field sparrow is an animal

Explanation:

Collins and Quillian's semantic network approach likened human memory to a computer and the model arranged human knowledge into nodes that were linked in order of hierarchy. Therefore, it would be easier for human knowledge to first link sparrow to sparrow, then field sparrow, then bird and finally as an animal for this case when following the hierarchy as proposed from the model.

A cylindrical metal specimen having an original diameter of 11.53 mm and gauge length of 51.4 mm is pulled in tension until frac

Verdich [7]

Answer:

a)Percent reduction in area=54.23 %

b)Percent elongation=32.87 %

Explanation:

Given that

Di= 11.53 mm

Df= 7.80 mm

Li= 51.4 mm

Lf= 68.3 mm

A= π/4 D²

a)

Percent reduction in area ,RA

$RA=\dfrac{A_i-A_f}{A_i}\times 100$

$RA=\dfrac{D_i^2-D_f^2}{D_i^2}\times 100$

$RA=\dfrac{11.53^2-7.8^2}{11.53^2}\times 100$

RA= 54.23 %

Percent reduction in area=54.23 %

b)

Percent elongation EL

$EL=\dfrac{L_f-L_i}{L_i}\times 100$

$EL=\dfrac{68.3-51.4}{51.4}\times 100$

EL=32.87 %

Percent elongation=32.87 %

drek231 [11]

Answer:

We use our knowledge of mixtures and solutions when we are designing new synthetic materials. This is especially the case in the biomedical field, where we have to deal with compatibility issues when placing materials made outside the human body into the body.We also design ways to help separate mixtures and solutions in industrial, commercial and environmental processes.

Hope this helps
