Answer:
<h3>Yes</h3>
Explanation:
If you build thing "a" and thing "a" builds thing "b" you <u>indirectly</u> build thing "b".
Answer:
2
Explanation:
So for solving this problem we need the local heat transfer coefficient at distance x,
We integrate between 0 to x for obtain the value of the coefficient, so
Substituing
The ratio of the average convection heat transfer coefficient over the entire length is 2
Answer:
The correct answer is True.
Explanation:
The feedback control system implies that to make a feedback, there must first be an error, otherwise there will be nothing to correct.
This system works so that there is an output that is controlled through a signal.
This signal will be feedback and it will signal an error which will be detected by a controller that will allow entry into the system.
In basic words, this system processes signals, samples them in the form of an output, and re-enters them feedback to detect the error signal.
Answer:
a) The planar defect that exists is twin boundary defect.
b) The planar defect that exists is the stacking fault.
Explanation:
I am using bold and underline instead of a vertical line.
a. A B C A B <u>C</u><u> </u>B A C B A
In this stacking sequence, the planar defect that occurs is twin boundary defect because the stacking sequence at one side of the bold and underlined part of the sequence is the mirror image or reflection of the stacking sequence on the other side. This shows twinning. Hence it is the twin boundary inter facial defect.
b. A B C A <u>B C B C</u> A B C
In this stacking sequence the planar defect that occurs is which occurs is stacking fault defect. This underlined region is HCP like sequence. Here BC is the extra plane hence resulting in the stacking fault defect. The fcc stacking sequence with no defects should be A B C A B C A B C A B C. So in the above stacking sequence we can see that A is missing in the sequence. Instead BC is the defect or extra plane. So this disordering of the sequence results in stacking fault defect.
