A 3" diameter germanium wafer that is 0.020" thick at 300K has 1.015 x 10^17 As atoms added to it. What is the resistivity of th
Ber [7]

Answer:

0.546 ohm / μm

Explanation:

Given that :

N = 1.015 * 10^17

Electron mobility, u = 3900

Hole mobility, h = 1900

Ng = 4.42 x10^22

q = 1.6*10^-19

Resistivity = 1/qNu

Resistivsity (R) = 1/(1.6*10^-19 * 1.015 * 10^17 * 3900)

= 0.01578880889 ohm /cm

Resistivity of germanium :

R = 1 / 2q * sqrt(Ng) * sqrt(u*h)

R = 1 / 2 * 1.6*10^-19 * sqrt(4.42 x10^22) * sqrt(3900*1900)

R = 1 /0.0001831

R = 5461.4964 ohm /cm

5461.4964 / 10000

0.546 ohm / μm

Research indicate that men and women of different races expectationz regarding to gender roles. Which of these statements regard
Ilia_Sergeevich [38]

Answer:

Asian American women are more likely than Asian American men to value egalitarian roles for men and women.

Explanation:

Gender biased has made the environment have different races expectation regarding to gender role.

A socialist feminine (Anita) believes that the oppression of women is based on the capitalist economy.

Parent influence an individuals on their lives socialization.

Some expectations of gender expectation.

1. Men are expected to gain more income, power, and social standing than females.

2. Using biological determinism, it shows that women are more hormonal and men are more aggressive.

3. Few percent of women are in the paid labor force while, large percent of men are in the paid labor force.

4. There is occupational segregation and this why women make up 97% of secretaries and 95% of child-care workers.

5. It is believed that women live longer than men, and this might be due to the stress the man has gone through during is life.

6. In general, men and women differ physically from but women have greater endurance than men.

There should be gender equality because *The Equal Pay Act of 1963" says that men and women receive equal pay for equal work.

Sexual harassment is a form of overt discrimination that has a negative impact on women's.

But today, both men and women say it is not fair for men to be the sole decision maker in the household.

Research on the impact of peer relationships on socialization have found that

1. for boys and girls peers reinforce age and racial norms as well as gender expectations.

2. gender norms are applied more strictly to boys than to girls.

3. homophobia serves to reinforce gender norms.

which process was found after wegeners time, helped scientists find out how the continents actually move.
Genrish500 [490]
I don't quite know what you're asking so I'll just go on a rant :) Wegener created and supported the continental drift theory, which stated that all of the continents once formed a super continent called Pangea. No one at the time believed in the theory though so he spent the rest of his life trying to find evidence to prove it. However, after he died scientists began to find information that supported his theory. When scientists began to study Earth's surface and the layers below, the theory of the tectonic plates was formed. This theory stated that Earth's crust, the lithosphere, was divided into twelve moving plates. This theory did in fact prove that Wegener's theory was correct. Another theory that proved Wegener's theory to be true was the process of Sea Floor Spreading. This theory stated that at divergent plate boundaries, new ocean floor was being created and the old was being pushed away from the boundary, the old sea floor would then be pushed to deep sea trenches created by convergent plate boundaries and essentially recycled back into the Earth. I hope this helped, sorry it is so long :)
