Vacuum tube experiments concluded that electrons, protons and neutrons are the fundamental particles of all atoms. Many hypothesis and experiments were proposed to know the distribution of these fundamental particles inside the atom. Thomson suggested a model of the spherical atom with positive charge distributed over the entire volume and electrons placed on it like plums on a cake. Rutherford tried to determine the structure of the atom experimentally.

Rutherford in 1911, carried out an experiment called ‘Gold foil experiment’ and could conclude the nature of an atom and the position of the protons present in the atom decisively. He also proposed the position and behaviour of electrons. They bombarded fragile sheets of gold foil with fast-moving alpha particles. Alpha particles, a type of natural radioactive particle, are positively charged particles with a mass about four times that of a hydrogen atom.

Observation of the experiment

Most of the alpha particles were indeed undeflected, a tiny percentage (about 1 in 8000 particles) bounced off the gold foil at extensive angles. Some were even redirected back toward the source.

Conclusion of the experiment

He concluded that all the positive charge and the majority of the mass of the atom must be concentrated in a minimal space in the atom’s interior, which he called the nucleus. The nucleus is the tiny, dense, central core of the atom and is composed of protons and neutrons.

Archimedes’ principle states that: “The upward buoyant force that is exerted on a body immersed in a fluid, whether partially or fully submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid”.

I have the sample paper

It state that "Put the thumb of your left hand along the direction of current passing through the conductor and then wrappe the finger around the conductor which shows the direction of magnetic field of the conductor".

Maxwell is an excellent scientist who give the theory of identifying the way and direction of magnetic field lines around a straight current carrying conductor..... This experiment is also called as.. "Maxwell's right hand thumb rule"?

The Maxwell's Screw Rules
The Maxwell Screw Rules sometime is also called the Maxwell's Corkscrew Rule. Imagine a right handed screw being turn so that it bores its way in the direction of the current in the wire. The direction of rotation gives the direction of the magnetic field.

  The first thing towards thinking carefully about the outcomes of democracy is to recognise that democracy is just a form of government. Democracy can only create conditions for achieving something.

StuB

The government can be accountable by framing and developing various laws and policies in which citizens can hold the government responsible if any of those policies and laws are not implemented or are held against the welfare of the citizens.

Reasons for democracy being accountable, responsive and legitimate Government

• The government can be responsible when people start taking actions when the government becomes insensitive about their aspirations.
• People can hold protests, carry out campaigns and organise rallies and force the government to respond to them.
• A democratic government is a legitimate government, as it is elected by citizens and enjoys the confidence and trust of the citizens.
• People have the right to choose their rulers and they have control over their rulers. Citizens can participate in decision making.
• Democracy makes the point that decision making is based on norms and procedures. So, a citizen who wants to know if a decision was taken through the correct procedures can find out this information.
• Citizens can take part in decision making whenever necessary.
• A democratic government is the people’s own government and it is run by the people.
• People wish to be ruled by representatives elected by them.

Hi

The short story "The Necklace" by Guy De Maupassant takes place in France several hundred years ago. Mathilde Loisel lives in a flat with her husband, who works as a clerk for the Minister of Education. Their lives are not luxurious, but they are not poor, merely simple. Mathilde, however, longs to be rich. She envies her friend Jeanne who has a large house and lots of jewelry. One day her husband brings home an invitation to a ball. He thinks his wife will be excited to attend such a fancy party, but instead she is upset. She complains that she has nothing suitable to wear to such an extravagant occasion. Her kind husband agrees to give her the four hundred francs that he had been saving to buy a new rifle to get herself a gown. The week of the party, Mathilde seems anxious again. When her husband asks her why, she frets that she has no jewelry to wear with her dress. He suggests that perhaps she could borrow something from her friend Jeanne Forestier. Mathilde goes to Jeanne's house and picks out a sparkling diamond necklace to borrow. She and her husband attend the gala and have a fabulous time. She loves amazing and dances all night. Finally, they head home in the wee hours of the morning. When they arrive home, Mathilde realizes that the necklace is missing. They wonder if it fell off in the carriage that they took home, but neither of them noticed the number. Her husband goes out to search the streets but returns empty handed. To stall for time, Mathilde writes to her friend that she broke the clasp and is having it repaired. In the meantime, they find another necklace that matches the missing one, but it costs thirty-six thousand francs. Her husband fortunately inherited eighteen thousand francs from his father, but they will need to borrow the rest of the money. Finally, they have enough to purchase the replacement necklace and Mathilde gives it to Jeanne who doesn't even look at it. The next ten years Mathilde's life changes dramatically. They move to a smaller apartment where she has to cook and clean for herself. She also does work on the side while her husband works multiple jobs to pay back all the money they borrowed. After the ten years, the money is all paid back, but Mathilde has aged a great deal. One day she sees Jeanne Forestier on the street. She decides to tell her the truth about the necklace. Jeanne is stunned by Mathilde's rough appearance. Mathilde explains that it is indirectly because of Jeanne since she lost the necklace she borrowed from her and had to pay for a replacement. Shocked, Jeanne confesses that the necklace Mathilde borrowed was a fake, made of paste, worth no more than five hundred francs. Clearly, the lesson of the story is that honesty is the best policy. If Mathilde had been honest with her friend from the start, she would have learned that the necklace wasn't made of real diamonds and would not have wasted ten years paying for a replacement.

Analytical Paragraph writing - An analytical paragraph is a form of descriptive writing which is written on the basis of a given chart, graph, data, outline, clues, table, etc. When writing an analytical paragraph, one should remember to describe the facts in the best possible manner and to cover the information provided.

The analytical paragraph has to be written in around 100-120 words. So the paragraph must use clear and crisp language along with providing complete details of the chart given in the question. There will be an internal choice given.

You need to attempt one question out of the two questions of analytical paragraphs given as a choice. The question carries 5 marks.

1. The introduction

The introduction is the first paragraph that should describe in brief what the graph is about. It should be like an opening paragraph that introduces the reader to the context of the chart given. When writing the introductory paragraph, you need not go into the details. You just need to mention what is clearly evident from the chart or the graph given in the question. It is best to write the introduction in one or two lines.

2. The body of the paragraph

This part of the analytical paragraph should contain details of the graph/chart given in the question. It should contain all the important information. It is extremely important to choose the significant details that should be included in the paragraph.
The body can be broken into two or three sub-paragraphs depending on the information extracted from the graph. Breaking the body into subparagraphs makes it easy for the reader to understand.
i. Organizing information: You should look for the large differences that are very prominent. You can mention the aspect which is the smallest or the largest in the data given. Any aspects that are similar should be mentioned next. You should further mention about the aspect that has remained unchanged or constant throughout.
ii. Comparing information: If the chart mentions two different parties, for example, men and women, refer to both of them in the analytical paragraph. If there is any contrast or comparison that could be drawn, you must present it effectively. If the chart is about a particular time period or highlights trends of several years, mention each year in a concise manner. If any comparison or contrast can be done for two or more years, you should write about it too.
iii. Mentioning quantities: When including numbers and figures, their accuracy must be ensured. There are a number of ways that can be used to describe quantities, for example- percentage, fraction, ratios, etc.
iv. Connecting sentences: If different information or ideas are there, you should use connectors or linking phrases to link them logically. The sentences of the paragraph should be sequential and connected rationally.

3. The conclusion

The last paragraph should summarise the idea mentioned and the information in general. It should be concluding in nature and act as the closing statement. One should keep in mind that one must not include any personal opinions, conclusions, or observations. You should simply stick to the facts.
You need not dispose of the information to write a good analytical paragraph. The key is to choose wisely the important information, organize it well, state correct facts and summarise it properly.

 

Thank you so much

Breathing	Cellular Respiration
Definition
Breathing involves the process of inhaling oxygen and exhaling carbon dioxide	Cellular respiration is the process of breaking down of glucose to produce energy, which is then used by cells to carry out the cellular function.
Process Occurrence
Breathing takes place in the lungs. Also involves the nose, mouth and pharynx	Respiration takes place in cells
Type of Process
Breathing is voluntary as well as an involuntary physical process. (For example, breathing during sleep is involuntary. Voluntary breathing is observed when we sing, speak, swim or for relaxation techniques)	Respiration is an involuntary chemical process.
Production of Energy
There is no production of energy in this process.	Energy is produced and released in the form of ATP.
Cellular Activity
As it occurs outside cells, it is called the extracellular process. (Occurs between the organism and the external environment)	As it occurs inside cells, it is called the intracellular process.

The outcomes of democracy are: Accountable , legitimate , responsive government: Democracy ensures free and fair elections. Economic growth and development: It is expected from democracy to bring economic development because, it works on the principle of equality.

If the atomic number is given from the electronic configuration we can find the poasition of the element.

Example:

Carbon (6)

Electronic configuration: (2,4)

No. of valence electrons gives the group number and no of shells gives period.

So it corrosponds to group 4 and period 2.

Recombination Prism is the prism which enables the recombining of the dispersed ray of light (VIBGYOR) into the ray of white light.

The bending of light or the refraction phenomenon is used to disperse a white light into VIBGYOR by first prism and the recombination prism due to its optical arrangement recombines VIBGYOR into the white light which was originally incident n the first prism.

According to Mandela, courage is not the absence of fear, but the triumph over it. The brave man is not he who does not feel afraid, but he who conquers that fear. He believed that if one had fear we should learn to conquer it and that is courageous man who do this.

Money eliminates this complex and tedious situation by representing an exchange medium which can be utilised for all commodities.

‘Double Coincidence of Wants’ is an important aspect of the barter system, wherein commodities are exchanged with each other without using money. Nevertheless, in an economy utilising money as an exchange medium, it does away with this by offering the essential intermediary step.

Till the First World War, industrial growth in India was slow. The war created a dramatically new situation. Manchester imports into India declined due to the war. The British factories became busy with producing things needed for the army. Indian mills now suddenly had a large market to supply. The long war made the Indian factories supply them with jute bags, cloth for army uniforms, tents and leather boots, horse and mule saddles, and a host of other items. Many workers were employed for longer hours. After the war Manchester goods lost their hold on the Indian markets. British economy collapsed as it could not compete with the USA, Japan, and its European rivals. The Indian industrialists captured the local market. Small scale industries prospered.

Gaston Roberge: Manikda, you seem to be upset? Did the people who were here upset you in any way?
Satyajit Ray: I’m unable to find my “Charulata” Screenplay missing.
Gaston Roberge: (speaking in Bengali) Do you know who stole it?
Satyaji Ray: Yes. I’m very sure of the culprit
G. R.: Then why the hesitation? (He got shocked by Ray’s reply)
S.R. : No, it will affect that famous personality’s reputation.
G.R. : I’m really shocked by your humbleness and human concern.
S.R.: Smiles and waves.
G.R. : Departs from that place.

 

Gregor Mendel conducted hybridization experiments on around 29,000 pea plants. Peas were an ideal choice for Mendel to use because they had easily observable traits there were 7 of which he could manipulate. ... He took years of breeding constant family lines to perfect the original constant traits.

The reason for the selection of pea plants for the genetic experiments are

• Easy to grow in the garden.
• The flowers of pea plants are hermaphrodite, i.e flowers have bisexual characteristics.
• Easy to obtain pure breed plant through self-fertilization
• The generation time of pea plants is less.

• They have excellent disease resistance and have an optimal rate of survival.

Mendal choose pea plant because they grow up within short duration of time and so that he can study more about generations quickly.They were also easily available. Also pea plants have many different characteristics like dwarfness, tallness , different colours of pea,etc.
