First one is D and Second one is B
Answer:
<h2>What are we supposed to write about</h2>
Explanation:
Answer:
a. chemical reaction
Explanation:
In both a dry and wet cell battery, electric currents are produced through chemical reactions.
Both cells are together called electrochemical cells.
- In these cells, chemical reactions produce an electric current.
- They are devices that converts chemical energy into electrical energy
- The reactions here are spontaneous redox reactions.
- This causes the current to flow on their own in the circuit.
Answer:
w = 11.211 KN/m
Explanation:
Given:
diameter, d = 50 mm
F.S = 2
L = 3
Due to symmetry, we have:
To find the maximum intensity, w, let's take the Pcr formula, we have:
Let's take k = 1
Substituting figures, we have:
Solving for w, we have:
w = 11211.14 N/m = 11.211 KN/m
Since Area, A= pi * (0.05)²
. This means it is safe
The maximum intensity w = 11.211KN/m
Technician A and B are correct . Because according to technician A, the cause written on the repair order is a diagnosis. Here, by diagnosis, he means that the problem is identified after examining the device and hence the judgement is made.
And according to B, you have to write the cause of the problems in the device that have been identified and the concern measures, which is also kind of diagnosis.
So, option D is correct.
