Why was Russia slow to modernize?

andriy [413]

Answer:

Russian modernization was slow to take place because the concepts of modernization conflicted with the autocratic power structure itself and amplified social conflicts in the country.

Explanation:

Alexander II, amid internal problems, sought to modernize the country and expand its domains in Asia. to this end, he abolished servitude and instituted wage labor on a large scale. Alexander II even established councils, the Ziemstvos, responsible for political participation in Russian lands, but still under the tutelage of the Tsar. Newspapers and magazines were created and, apparently, Russia was moving towards political modernization.

However, ethnic minorities organized themselves and demanded autonomy or political apparatus of representation within the Empire, which affected the autocratic power of the tsar. Alexander II responded to these movements with the force of arms, and massacres were perpetrated by his order. As it was understood that the modernization of the country threatened the autocracy of the current government, the Tsar decided to delay the modernization of the country.

The city of Oakland is experiencing a movement of its population to the suburbs. At present 85% of the total population lives in

Oxana [17]

Answer:

A. $\left[\begin{array}{cc}0.93&0.07&\\0.01&0.99&\end{array}\right]$

B. (0.85 0.15)

C. 79.2% population in the city while 20.8% population in the suburb

Step-by-step explanation:

(a) The transition matrix for the information is

C S

$\left[\begin{array}{cc}0.93&0.07&\\0.01&0.99&\end{array}\right]$

(b) the probability vector for the information is

$(\frac{85}{100} \ \ \frac{15}{100} )$

and this gives us

(0.85 0.15)

(c) we simply multiply the above two matrices to find the percent of the population can be expected to be in each category after one year after

$\left[\begin{array}{cc}0.85&0.15\end{array}\right] \left[\begin{array}{cc}0.93&0.07&\\0.01&0.99&\end{array}\right] = \left[\begin{array}{cc}0.792&0.208&\end{array}\right]$

in the city there are 79.2% while in the suburb, there are 20.8%

The quantum state of a particle can be specified by giving a complete set of quantum numbers (n,l, ml,ms). how many different qu

ipn [44]

To find the total number of allowed states, first, write down the allowed orbital quantum numbers l, and then write down the number of allowed values of ml for each orbital quantum number. Sum these quantities, and then multiply by 2 to account for the two possible orientations of spin.

Quantum states for n=5
l......ml
0 , 0................................1
1 , -1, 0, +1................................ 3
2 , -2, -1, 0, +1, +2................................5
3 , -3, -2, -1, 0, +1, +2, +3................................ 7
4 , -4,-3, -2, -1, 0, +1, +2, +3,+4 ................................9

2*(1+3+5+7+9)=
2*5^2 = 50 allowed states

Andreyy89

Answer:

Step-by-step explanation:

for odd terms

first term=5

c.d.=8-5=3

odd terms are given by 5+3(n-1)=2+3n

for even terms

first term=10

c.d.=13-10=3

even terms are given by 10+3(n-1)=7+3n
