Bureaucracy stands for the government officers and it includes all the government servants who hold office on permanent basis till they retire at a fixed age.
Bureaucracy, generally, means government by the officers and it includes all the government servants who hold office on permanent basis till they retire at a fixed age. Head of the State and ministers determine the policy. Permanent government servants run the administration and enforce the laws according to that policy. There is no effect on them of the change of head of state and the ministers.
Bureaucracy has been derived from the French word ‘bureau’ which means ‘desk’. Thus, bureaucracy is a government which is run by the persons who sit on desks, means officers.

universal set is the set which contain all subsets of other sets and it is denoted by U.
A subset is a set which contain elements of other set.
nullset or empty set does not contain any element
(i)A={x:x is the multiple of 0 <x>18}
Gaurav Seth 5 years, 6 months ago
Any Set that does not contain any element is called the empty or null or void set. The symbol used to represent an empty set is – {} or φ. Examples:
- Let A = {x : 9 < x < 10, x is a natural number} will be a null set because there is NO natural number between numbers 9 and 10. Therefore, A = {} or φ
- Let W = {d: d > 8, d is the number of days in a week} will also be a void set because there are only 7 days in a week.

A universal set is a set which contains all the elements or objects of other sets, including its own elements. It is usually denoted by the symbol ‘U’.
Suppose Set A consist of all even numbers such that, A = {2, 4, 6, 8, 10, …} and set B consist of all odd numbers, such that, B = {1, 3, 5, 7, 9, …}. The universal set U consist of all natural numbers, such that, U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10,….}. Therefore, as we know, all the even and odd numbers are a part of natural numbers. Therefore, Set U has all the elements of Set A and Set B.

The power set is a set which includes all the subsets including the empty set and the original set itself. It is also a type of sets. If set A = {x,y,z} is a set, then all its subsets {x}, {y}, {z}, {x,y}, {y,z}, {x,z}, {x,y,z} and {} are the elements of powerset, such as:
Power set of A, P(A) = {x}, {y}, {z}, {x,y}, {y,z}, {x,z}, {x,y,z} and {}
Where P(A) denotes the powerset.

Ans. When the author got a room of his own in the city home, the old lady accepted her aloofness calmly. She worked on her spinning wheel all day long and recited her prayers. Only in the afternoon did she take a half-hour break to rest and to feed the birds.

Van der Waals equation is an equation relating the relationship between the pressure, volume, temperature, and amount of real gases. For a real gas containing ‘n’ moles, the equation is written as;
{tex}\left( P+\frac{a{{n}^{2}}}{{{V}^{2}}} \right)\left( V-nb \right)=n\,R\,T\,(P+V2an2)(V−nb)=nRT{/tex}
Where, P, V, T, n are the pressure, volume, temperature and moles of the gas. ‘a’ and ‘b’ constants specific to each gas.
The equation can further be written as;
- Cube power of volume: {tex}{{V}^{3}}-\left( b+\frac{RT}{P} \right){{V}^{2}}+\frac{a}{P}V-\frac{ab}{P}=0V3−(b+PRT)V2+PaV−Pab=0{/tex}
- Reduced equation (Law of corresponding states) in terms of critical constants:
{tex}\left( \pi +\frac{3}{{{\varphi }^{2}}} \right)\left( 3\varphi -1 \right)=8\tau :\,\,where\,\,\pi =\frac{P}{Pc},\varphi =\frac{V}{Vc}\,\,\,and\,\,\tau =\frac{T}{Tc}(π+φ23)(3φ−1)=8τ:whereπ=PcP,φ=VcVandτ=TcT{/tex}

Taplow narrates the incident about one day when Mr. Crocker Harris made one of his classical jokes in the class which no one understood.
Taplow laughed out of politeness. Instead of feeling thankful, Mr. Crocker Harris asked Taplow to explain the joke to the class.
This incident proved that Mr. Crocker Harris did not like 'being liked'.

PPC is concave to the origin because of increasing Marginal opportunity cost. This is because inorder to increase the production of one good by 1 unit more and more units of the other good have to be sacriced since the resources are limited and are not equally efficient in the production of both the goods.
