Subject: Illicit selling of liquor deadly chemicals like anthrax

Sir:

I am writing this letter to your good self to express my deep concern over the issue of illicit selling of liquor and deadly chemicals like anthrax in our country. Illicit liquor may contain excess amount of alcohol and other dangerous chemicals. Easy availability of illicit liquor tends to make the youth addict to it.  

Chemicals like anthrax can easily be misused by terrorists or anarchists to spread terror in societies.  

Through the medium of your daily I appeal to the concerned authorities to look into the matter and take strict action against culprits who are making such deadly substances easily available to the youth and anti-social elements. I hope you will give my views enough space your daily for awareness and caution.

Yours truly,

Himakshi

The Indian National flag is a tricolor(saffron, white and green) flag with the Ashoka Chakra in navy blue at the center. Each color represent some values of human life,

• Saffron: Renunciation or disinterestedness. The leaders must dedicate themselves to the work and should be indifferent to material gains.
• White: Light. It denotes the path of truth
• Green: Relation to the soil.
• Ashoka Chakra: Wheel of the law of dharma.  Those who work under this flag are abiding under dharma. It also denotes the motion. Where it represents India will accept change and move forward.

Procedure: Place the chair next to a wall & mark 8 feet in front of the chair. The subject starts by fully seated, hand resting on knees & feet flat on ground. On command ‘Go’ timing is started & the subject stands & walks as quickly as possible around the cone. Back to initial position and sit on to chair. A Person sit down Stop time. Perform two trials.

Steps to form Committees for Tournaments: Sports events are organised at various levels which include district, state, national or international levels’ Such tournaments require careful planning in order to be successful’ Committees are formed at various levels. A letter is sent to all concerned for participation.
Various steps are:

• Meetings are conducted at regular interval.
• Experts in various areas are identified.
• Pre-meet work organising committee is set up for the purchase of equipment, layout of courts, etc.
• Welcome/Reception committee and a Technical committee to officiate during the sports meet is also formed. 

A person develops a posture on the basis of the personality.

Everyone has a personality ( a unique combination of behavioral and emotional characteristics). Our personality makes us who we are inside and then develop a posture on the basis of these characteristics.

For example, confident people possess a strong and powerful posture as compared to introverts who often adopt a sway-back posture.

Please ask question with complete information.

Poor rag-pickers like Saheb spend the early years of their lives looking for gold in garbage dumps. The parents of these street children have no fixed income. They wage war against poverty and hunger. They have no dreams except finding the means of survival. Garbage to them is gold. It is the source of their daily bread and provides a roof over their heads. He ends up as a servant at a tea-stall and loses his freedom.
Mukesh, the son of a poor bangle-maker of Firozabad, has a dream of becoming a motor mechanic. He wants to learn to drive a car. He thinks of joining a garage to fulfil his dream. He knows that the garage is far away, yet he has decided to walk. He realises the reality and is willing to overcome the obstacles. His daring to rise and decision to get free from the trap laid by vicious moneylenders and middle men arouse a sense of hope.Deprived of education, proper food and upbringing, these children are forced into labour early in life. 

Rutherford passed beams of alpha particles  through a  thin gold foil to observe the atom and noted how the alpha particles scattered from the foil.

Observations of Rutherford's alpha ray scattering experiment:

1.Most of the α-particles passed straight through the gold foil without any deviation.

2. Some of the α-particles were deflected by the foil by some angles.

 3.Interestingly one out of every 12,000 alpha particles appeared to rebound

Conclusion of Rutherford's scattering experiment:

1.Most of the space inside the atom is empty because most of the α-particles passed through the gold foil without getting deflected.

2. Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space.

 3. A very small fraction of α-particles were deflected by very large angles, indicating that all the positive charge and mass of the gold atom were concentrated in a very small volume within the atom.

Kirchhoff’s First law: Junction law

• Junction Law is also known as Kirchhoff’s First Law.
• It states that at the junction,sum of current entering the junction is equal to the sum of current leaving the junction.
• Junction is any point in the circuit.

Kirchhoff’s Second law: Loop law

• Loop law is also known as Kirchhoff’s Second Law.
• It states that in a closed loop,algebraic sum of Emfsis equal to the algebraic sum of product of resistances and respective currents flowing through them.
• Consider a simple circuit havingEmfs = E₁ and E₂; R₁ and R₂ =resistances; current =I₁ and I₂.
• Then according to this law : E₁+E₂=I₁R₁+ I₂R₂

Lenz’s law

• According to Lenz’s law:-The polarity of the induced emf is such that it tends to produce induced current in such a direction that it opposes the change in magnetic flux that produced it.
• The (-) ive sign in given equatione= (-) (dΦ/dt)tells about the direction.
• According to Faraday’s law whenever there is change in the magnetic flux, emf is induced, as aresult there will be induced current.
• According to Lenz’s law the direction of the induced current will be such that it opposes the change in the magnetic flux.

Magnetic flux is defined as the number of magnetic field lines passing through a given closed surface. It provides the measurement of the total magnetic field that passes through a given surface area. Here, the area under consideration can be of any size and under any orientation with respect to the direction of the magnetic field.

Magnetic Flux Symbol

• Magnetic flux is commonly denoted using Greek letter Phi or Phi suffix B.
• Magnetic flux symbol: Φ or Φ_B.

Character of M. Hamel

M. Hamel was a true French man. Teaching at Alsace for forty years, he had become a part of its people. He was an honest teacher. He did not blame his students alone for poor learning. He also held himself responsible for the same. He was very patriotic as he appealed to his countrymen to hold fast to their mother tongue to be free from the Prussians. According to him the French language was the most beautiful, the clearest and the most logical language in the world. He appealed to his countrymen to guard it and never forget it. He was emotionally attached to the school and all his students. However, he was very brave and strong. He was really sorry for not making sincere efforts to teach French to his countrymen. At the end, he became so emotional that he could not speak
