Answer:
R = 31.9 x 10^(6) At/Wb
So option A is correct
Explanation:
Reluctance is obtained by dividing the length of the magnetic path L by the permeability times the cross-sectional area A
Thus; R = L/μA,
Now from the question,
L = 4m
r_1 = 1.75cm = 0.0175m
r_2 = 2.2cm = 0.022m
So Area will be A_2 - A_1
Thus = π(r_2)² - π(r_1)²
A = π(0.0225)² - π(0.0175)²
A = π[0.0002]
A = 6.28 x 10^(-4) m²
We are given that;
L = 4m
μ_steel = 2 x 10^(-4) Wb/At - m
Thus, reluctance is calculated as;
R = 4/(2 x 10^(-4) x 6.28x 10^(-4))
R = 0.319 x 10^(8) At/Wb
R = 31.9 x 10^(6) At/Wb
The critical path is A-B-C, with a duration of 15 minutes.
<u>Explanation</u>:
- The critical path is A-B-C, with a term of 15 minutes. You don't need to be knowledgeable in computer lingo to make sense of this one (as I made sense of it absent a lot of data on that half of the condition). Here's the manner by which I made sense of this.
-
The main thing I saw was that "predecessor" was utilized, which implies something precedes the other thing. That provided me the primary insight that A precedes B and C, and that B must precede C. Then, I just included the term times for the three ways, which allowed me 15 minutes.
Answer:
labelled diagram for combination wrench
Explanation:
Althought she referenced the article at the end, is imposible to know which part of the article is hers and which part is the expert's so that would be plagiarism.
If she used quotation marks in the words of the expert it would be clear and no plagiarism could be accused.
Answer:
0.156 V
Explanation:
Analog to digital converter (ADC) is used to convert an analog signal into a digital signal.
Resolution of ADC means in how many parts the signal of interest can be divided.
The resolution can be found using
Q = Full scale Voltage range/2^M
Where the full scale voltage range is 10 V and M is the number of bits of the ADC.
Q = 10/2^6
Q = 10/64
Q = 0.156 V
Therefore, the smallest voltage difference that can be detectable by this ADC is 0.156 V
