b) MEAN. HoPe It HeLpS yOu??

Yogita Ingle 5 years, 3 months ago (2577571)

Mean cannot be determined by graphical method.

Mean is the sum of the values of a subject divided by number of values.

As it is a single value and cannot be compared and represented in different values the determination of mean by the graphical method is not possible.

Mean is a perfect method for the determination of the central tendency of a value.

Sneha Bhardwaj 3 years, 4 months ago (11960018)

Maya , a girl of 10, and her brother Nishad, a boy of 7, were very curious about one Mr.Nath who had been living at Shankar House for over an year and was their mother's patient. He was a very lonely and thin man and looked starved. Maya was of the opinion that he was a criminal on the run and had lots of money stacked somewhere in his room while Nishad, on the other hand, was considering the possibility of him being just a poor, friendless soul who had no proper means to sustain himself. However, one thing that both agreed on was that there was something peculiar and strange about Mr. Nath. One day while playing one of their marbles went into Mr. Nath's room and to extract it the children went there. For once, they had a look at Mr. Nath and since began debating about him and his possible profession. Maya interpreted the burn marks on his face to be caused by a fire started by the police to turn him out of his house. Nishad thought it to be too far-fetched though he did not have much in defence of the man. On the Monday after their mamma's birthday, as Maya had to spend the day with a school friend, Nishad went to Mr. Nath's room alone and offered him a chocolate bar considering his emaciated state. When he later told of his encounter with the man to Maya, she was disappointed that she missed it but wanted to know more about whatever else her brother had found out. Nishad had had a talk with Ramesh, who carried food from the restaurant to the strange man's room, and found out that every Sunday a talkative tall, fair, stout and bespectacled man came to visit Mr. Nath. He also found out that Mr. Nath though did not care what food was brought to him, tipped Ramesh well. Maya interpreted it all as a great conspiracy and saw the bespectacled man as an accomplice to Mr. Nath, visiting him to give part of the money they had looted together. Nishad wondered at his sister's imagination and thought Mr. Nath quite ordinary. Maya rejected Nishad's idea further adding that many criminals are usually ordinary looking. The next day their school was to reopen after the summer holidays but, because of incessant rain they enjoyed another holiday. Maya took a paper and decided to jot down the developments in the mystery of Mr. Nath's identity. She shared it with her brother and talked about various points like many being scared of Mr. Nath, his not receiving any mail ever, his unfriendly nature, having just one friend-a possible accomplice and so on. Nishad countered Maya at various points but was constantly put down by her who just wanted to prove that Mr. Nath was a criminal. Nishad did not like this attitude and asked Maya to stop always referring to the man as a criminal. Maya pointed out the futility of all their snooping if it was not so but Nishad said that it was not necessary for the man to be a criminal for him to want to know about him. He stormed out of the room saying that he would become the lonely man's friend. Maya noticed his adamant take on the matter and that her theory had had no effect on him

Mr. Nath, was a neighbor of the children at Shankar House. He lived alone, kept to himself and often sought medical treatment from the children's mother. We do not have any clear evidence on the character of Mr. Nath, who had mixed reviews from the neighbors, who thought he was quite rude and mad, while Nishad and his mother, thought Mr. Nath was a harmless man and rather polite. The reader is free to make any assumptions on Mr. Nath, provided they are logical and well-backed by facts from the story.

Properties of solids

  • Solid has fixed volume.
  • Solid has fixed shape.
  • Solid has high density.
  • Solids are heavy.
  • Solid does not flow.

Properties of liquid

  • Liquid has definite volume.
  • Liquid has no definite shape.
  • Liquid gets the shape of container in which it is kept.
  • Liquid cannot be compressed much.
  • Liquid has less density compare to solid.
  • Liquid is lighter than solid.
  • Liquid flows and hence is called fluid.

Properties of gas

  • Gas has indefinite shape
  • Gas has no fixed volume.
  • Gas gets the shape and volume of container.
  • Gas fills the container completely.
  • Gas has very low density.
  • Because of low density gas are light.
  • Gas can flow easily and hence are called fluid.

When a capacitor is charged by a battery, work is done by the charging battery at the expense of its chemical energy. This work is stored in the capacitor in the form of electrostatic potential energy.

Consider a capacitor of capacitance C. Initial charge on capacitor is zero. Initial potential difference between capacitor plates = zero. Let a charge Q be given to it in small steps. When charge is given to capacitor, the potential difference between its plates increases. Let at any instant when charge on capacitor be q, the potential difference between its plates V=q/C

Now work done in giving an additional infinitesimal charge dq to capacitor

dW = V dq = q/C dq

The total work done in giving charge from 0 to Q will be equal to the sum of all such infinitesimal works, which may be obtained by integration. Therefore total work

Ferrous sulphate crystals contain water molecules as water of crystalisation - (FeSO4. 7H2O). 
On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed.

Due to this, it's colour changes from light green to white.

Apartheid- It was the policy of social discrimination followed in South Africa. This policy divided the people and labelled them on the basis of their skin colour. Under this system, blacks were forbidden from living in white areas. Trains, buses, hotels, hospitals, schools and colleges, libraries, cinema halls, public toilets, etc. were all separate for white and blacks. In South Africa, white did not give equal rights to the native Africans.

India had raised this issue first time in United Nations General Assembly in 1946.

It was due to the constant moral support of India and the continuous struggle of Dr. Nelson Mandela, the policy of apartheid has been abolished in South Africa in 1990.

Size of the particles < 1nm 1– 1000nm >1000nm
       
Nature Homogeneous Heterogeneous Heterogeneous
       
Filterability(Diffusion through parchment paper) Particles of true Solution diffuse rapidly through filter paper as well as parchment paper. Colloidal particles pass through filter paper but not through parchment paper. Suspension particles do not pass through filter paper and parchment paper.
       
Visibility Particles of True Solution are not visible to naked eye. Colloidal particles are not seen to naked eye but can be studied through ultra microscope. Suspension particles are big enough to be seen by naked eye.
       
Tyndall effect True Solution does not show Tyndall effect. Colloids shows Tyndall effect. Suspension may or may not show Tyndall effect.

Different properties of solutions are as follows:

  • It is a homogeneous mixture.
  • Its particles are too tiny and have a diameter less than 1 nm.
  • The particles are not visible to naked eyes.
  • Particles don’t scatter a beam of light passing through it and hence the path of the light is not visible.
  • Solutes are inseparable from the mixture and do not sediment. A solution is stable.
  • The components of a mixture cannot be separated using filtration.
