EIFFEL TOWER The Eiffel Tower was built in 1889 for the Universal Exposition celebrating the centenary of the French revolution. The Prince of Wales‚ later King Edward VII of England opened the tower‚ which had been chosen from 700 proposals submitted in a design competition.

Strength training typically produces a combination of the two different types of hypertrophy: contraction against 80 to 90% of the one repetition maximum for 2–6 repetitions (reps) causes myofibrillated hypertrophy to dominate (as in powerlifters‚ olympic lifters and strength athletes)‚ while several repetitions (generally 8 – 12 for bodybuilding or 12 or more for muscular endurance) against a sub-maximal load facilitates mainly sarcoplasmic hypertrophy (professional bodybuilders and endurance athletes)

of 50 grams of sucrose (C12H22O11) in 400 grams of water will freeze. The molecular weight of sucrose is 12(12.01) + 22(1.01) + 11(16.00) = 342.34 g/mole so‚ the number of moles of sucrose is and the concentration of the solution in moles per kilogram of water is By taking the freezing point constant for water as 1.86 from Table and then substituting the values into the equation for freezing point depression‚ you obtain the change in freezing temperature: Δ Tf = 1.86°C/m × 0.365 m = 0.68°C

Toy cars have been played with by children for many years. Would one wonder the way a model or toy car rolls down a hill? One would think it would be because it has wheels‚ this is true but there is more to a car rolling downhill than it having wheels. Gravity is the force that is keeping all things on the ground. The heavier an object is the more gravity has an effect on its momentum. If you put a toy car on a downhill slope it will begin to roll because of gravity. The more the car weighs will

and is sometimes used as a unit of measurement‚ e.g. a 0.3 molar solution of HCl. In that example‚ there would be 3 moles of HCl for every 10 litres of water (or whatever the solvent was). Molality Molality is the number of moles of solute per kilogram of solvent. It

At a camera factory‚ an inspector checks 20 cameras and finds that three of them need adjustment before they can be shipped. Another employee carelessly mixes the cameras up so that no one knows which is which. Thus‚ the inspector must recheck the cameras one at a time until he locates all the bad ones

------------------------------------------------- Agriculture Agriculture‚ also called farming or husbandry‚ is the cultivation of animals‚ plants‚ fungi‚ and other life forms for food‚ fiber‚ biofuel and other products used to sustain human life. Agriculture in India has a significant history. Today‚ India ranks second worldwide in farm output. Agriculture and allied sectors like forestry andfisheries accounted for 16.6% of the GDP in 2009‚ about 50% of the total workforce.[1] The economic contribution
