*** **Please solve Problem 3 using MATHCAD** I am
unsure how to properly use MATHCAD so this would be a tremendous
help. Thank you

1.

A Si diode doped with ND=2x1016 cm-3 and NA=2x1017 cm-3. The area of the diode is 5m x5 m. If the voltage across the diode is zero:

a) Calculate the majority and minority carrier concentrations for the n-side, nn0 and pn0.

b) Calculate the majority and minority carrier concentrations for the p-side, pp0 and np0.

c) Calculate Vbi.

d) Calculate W for the above diode.

e) Calculate xn0 and xpo for the diode above.

f) Calculate Em for the device above.

g) Calculate CJ for the above diode.

Problem 2:

3.

Problem 3:

Repeat (a) to (g) of problem 1, if a reverse bias voltage VR = ̶ 10V is applied.

***** PLEASE solve using MATHCAD, I am unsure on how to solve
properly with this application. Thank you so much!
Problem 7:
Design a Silicon diode that has a breakdown voltage =20V and has
a junction capacitance of 1 pF at no biasing.

Hello, I am working on an assignment but I am unsure of how to
solve it. Please help me. The assignment details are below.
Consider this scenario:
Your friend starts a website, nothingbutflags.com, which is not
making money. Your friend asks you to help generate more traffic.
You ask your friend how much traffic the website had last month?
And your friend replies and says only 500 visits. You also ask how
many flags did you sell? Your friend replies...

:
import csv
import requests as r
from bs4 import BeautifulSoup
urltoget =
'a.ttu.edu/2019c/isqs6339/http://drd.bhw1/index.php'
filepath = 'C:\\Users\\Zuliat\\Desktop\\test123.csv'
res = r.get(urltoget)
res.content
if res.status_code == 200:
print (' request is good')
else:
print (' bad request, retrieved code' + str(res.status_code))
print (res.content)
soup = BeautifulSoup(res.content,'lxml')
print(soup.title)
They are responding with a message Line 1

You are studying the source of new virus that has recently
infected humans. You suspect that the virus was transferred from
other primates (they exhibit a similar infection), specifically
chimpanzees, gorillas, or orangutans. You sample blood from several
infected humans and sequence some viral genes. You then build a
phylogenetic tree with the human sequences and all the known
strains from each primate. Draw a hypothetical...

I am buying a firm with an expected perpetual cash flow of $630
but am unsure of its risk. If I think the beta of the firm is zero,
when the beta is really 1, how much more will I offer for
the firm than it is truly worth? Assume the risk-free rate is 6%
and the expected rate of return on the market is 18%.
(Input the amount as a positive value.)
