Internet is also known as the World Wide Web (www) is a global system of interconnected computer networks that use a protocol called the Internet Protocol Suite (TCP/IP) to link to billions of devices all around the world. The impact of this has been so enormous that it has been referred to as the 8^th continent of the world. This carries a vast range of information, from the top-secret military and research files to the most trending and viral video of the week. This massive storage is shared by everyone, with everyone’s computer contributing to the ever-expanding treasure trove of knowledge.

The definition of courage for Mandela was to win and attain victory over fear. For him, the absence of fear was not the meaning of being courageous.

In a chemical reaction chemical equilibrium is defined as the state at which there is no further change in concentration of reactants and products.
For example,

At equilibrium the rate of forward reaction is equal to the rate of backward reaction. Equilibrium mixture: The mixture of reactants and products in the equilibrium state is called an equilibrium mixtures.
Based on the extent to which the reactions proceed to reach the state of equilibrium, these may be classified in three groups:
(i) The reactions which proceed almost to completion and the concentrations of the reactants left are negligible.
(ii) The reactions in which most of the reactants remains unchanged, i.e. only small amounts of products are formed.
(iii) The reactions in which the concentrations of both the reactants and products are comparable when the system is in equilibrium.

Dear Sir

Sub : Switch to Solar power

I wanted to bring to your attention the case of the rising electricity bills in Delhi. Owing to the severe scorching heat most households are using air-conditioners through the day and night. Coupled with the other daily usages, the monthly bill is hitting the roofs.

I strongly feel that people should switch over to Solar energy as an alternative immediately. It is a renewable source of energy, environment friendly and a great way to reduce the bills.

Kindly take this issue up in your daily and encourage people to make this transition. We look forward to getting like wise suggestions and possibilities of solutions to the every day problems of citizens.

Yours sincerely
