I’m just answering this for points sorry mate
A design brief should highlight the problem and specifications for the solution.
<h3>What is an electrical circuit?</h3>
An electrical circuit can be defined as an interconnection of different electrical components, in order to create a pathway for the flow of electric current (electrons) due to a driving voltage.
<h3>The components of an electrical circuit.</h3>
Generally, an electrical circuit comprises the following electrical components:
<h3>What is a design brief?</h3>
A design brief can be defined as a short statement which is written to describe the need of an individual or business, and what type of solution will meet that need (problem) through the design of an electrical circuit.
This ultimately implies that, a design brief should highlight the problem and specifications for the solution.

Answer:
35
Explanation:
so you said 140 in total and it's a square
it's basically finding the perimeter of the square
so 35 is each side of the square that I am imagining in my head
so if you add 35...4 times you will get 140
for example:35
35
35
+ <u>3</u><u>5</u>
<u>1</u><u>4</u><u>0</u><u> </u>
or 35×4=140
Answer:
(a) Precipitation hardening - 1, 2, 4
(b) Dispersion strengthening - 1, 3, 5
Explanation:
The correct options for each are shown as follows:
Precipitation hardening
From the first statement; Dislocation movement is limited by precipitated particles. This resulted in an expansion in hardness and rigidity. Precipitates particles are separated out from the framework after heat treatment.
The aging process occurs in the second statement; because it speaks volumes on how heated solutions are treated with alloys above raised elevated temperature. As such when aging increases, there exists a decrease in the hardness of the alloy.
Also, for the third option for precipitation hardening; This cycle includes the application of heat the alloy (amalgam) to a raised temperature, maintaining such temperature for an extended period of time. This temperature relies upon alloying components. e.g. Heating of steel underneath eutectic temperature. Subsequent to heating, the alloy is extinguished and immersed in water.
Dispersion strengthening
Here: The effect of hearting is not significant to the hardness of alloys hardening by the method in statement 3.
In statement 5: The process only involves the dispersion of particles and not the application of heat.

the others dont make sense to be an engineer
