Answer:
Both of them are wrong
Explanation:
The two technicians have given the wrong information about the wires.
This is because firstly, a higher rating of AWG means it is smaller in diameter. Thus, the diameter of a 18 AWG wire is smaller than that of a 12 AWG wire and that makes the assertion of the technician wrong.
Also, the higher the resistance, the smaller the cross sectional area meaning the smaller the diameter. A wire with bigger cross sectional area will have a smaller resistance
So this practically makes the second technician wrong too
Answer:
1.1451 x 104 (11451.13)mg/m3
Explanation:
1 ppmv is defined as one volume of a contaminant or solid(CO)(mL) in 1 x 106 volume of solvent/water.
1ppmv = 1mL/m3
Concentration in mg/m3 = volume in ppm x molecular weight x pressure(kPa)/( gas constant x temperature(K)
Molecular weight of CO = 12 + 16
= 28g/mol
Temperature = 273.15 + 25
= 298.15K
Pressure = 1 x 101.325kPa
= 101.325kPa
Ppmv = 1 x 10-4ppmv
Gas constant, R = 8.3144 L.kPa/mol.K
Concentration in mg/m3 = (1 x 104 * 28 * 101.325)/(8.3144 * 298)
= 1.1451 x 104mg/m3
= 11451.13 mg/m3

Question:
Which statement best explains how Sarah Zielinski introduces and develops her points in the article about Henrietta Lacks?
- Zielinski explains how her interest in the Henrietta Lacks story began then provides details about the first immortal human tissue sample and tells why it has been both important and controversial.
- Zielinski explains the need for using human tissue samples then introduces Rebecca Skloot who gives an account of her experiences of researching the origin of the HeLa cells.
- Zielinski explains how the first immortal human cells were found then provides Rebecca Skloot’s answers to questions about the importance of using human tissue samples, the Lacks family’s responses to learning of its link to the HeLa cells, and the issues arising from their discovery and use.
- Zielinski explains the importance of the first human tissue samples to life and their widespread use, the reason for the confusion about those samples as well as the ethical issues faced by the Lacks family after learning they had not shared in profits from the sale of the HeLa samples.
Answer:
The correct answer is number 3
Explanation
The article devotes the first three sentences to describing how the Immortal cells came to be. In sentence 4, she makes reference to a book by Rebecca Skloot titled <em>The Immortal Life of Henrietta Lacks. </em>The book explains the history of Henrietta's cells and its impact on Henrietta's family as the medical world.

Answer:
Explanation:
Given data:
P_1 power = 20 dBm = 0.1 watt
coupling factor is 20dB
Directivity = 35 dB
We know that
coupling factor 
solving for final power
Directivity 
output Power
