Answer:
a) 316 stainless steel
b) 316 stainless steel
c) Carbon steel
d) stainless steel 316
e) stainless steel 316
f ) Carbon steel
Explanation:
<u>A) A 10,000 M' storage tank for Toluene</u>
The best material for building this tank is 316 stainless steel this is because it is relatively cheaper than other materials such as Hest Alloy C while still maintaining the required tensile strength needed to build the storage tank for Toluene
<u>B) A 5.0 m' tank for storing a 30% w/w aqueous solution of sodium chloride </u>
The suitable material for building this tank is 316 stainless steel as it is cheaper than Titanium and Hest Alloy C and it is compatible with sodium chloride
<u>C) A 2 m diameter, 20 m high distillation column, distilling acrylonitrile </u>
The best material for constructing this column is Carbon steel and this is because it has a very high compressive strength which is approximately . 1320 MPa
<u>D) A 100 m storage tank for strong nitric acid.</u>
The best material is stainless steel 316 and this is due to its high tensile strength
E) 316 stainless steel
F) Carbon steel is suitable for building this absorption column because it has a very high compressive strength which is approximately . 1320 MPa
Answer:
Researcher Timothy Salthouse proposes that if the person is mentally active throughout their lives, they will have a cognitive reserve in late adulthood that will help them continue to execute a high mental level.
Explanation:
The psychologist Timothy Salthouse focused his research on cognitive aging, and his study is considered very important in the area since it helped identify the first signs of cognitive impairment.
The psychologist Salthouse considered that if the person had an excellent cognitive reserve would not be strongly affected by the brain deterioration that occurs over the years.
The cognitive reserve is the competition that the brain has to balance the deterioration that occurs over the years in people. This cognitive reserve is related to the actions that the brain performed previously, habits, and knowledge acquired by the person over time.
Therefore, older adults who have taken actions to strengthen their cognitive processing will have better advantages in obtaining the cognitive reserve.

Answer:
The limits of the hole size are;
The maximum limit of the hole diameter 0.255
The minimum limit of the hole diameter = 0.245
Explanation:
Tolerance is a standardized form of language that can be used to define the intended 'tightness' or 'clearance' degree between mating parts in a mechanical assembly process and in metal joining processes such as welding and brazing processes
In tolerancing, the size used in the description of a part is known as the nominal size while allowable variation of the nominal size that will still allow the part to function properly is known as the tolerance
A tolerance given in the form ±P is known as bilateral tolerancing, with the value being added to or subtracted from the nominal size to get the maximum and minimum allowable limits of the dimensions of the nominal size
Therefore;
The given nominal dimension of the hole diameter = 0.250
The bilateral tolerance of the dimension, = ±0.005
Therefore;
The maximum limit of the diameter of the hole = 0.250 + 0.005 = 0.255
The minimum limit of the diameter of the hole = 0.250 - 0.005 = 0.245
