Q:

Why is argon gas used along with tungsten wire in an electric bulb?

A) To increase the life of the bulb B) To reduce the consumption of electricity
C) To make the emitted light colored D) To reduce the cost of the bulb
 
Answer & Explanation Answer: A) To increase the life of the bulb

Explanation:

Argon gas is used in fluorescent and incandescent light bulbs to stop the oxygen in the light bulbs from corroding the hot tungsten filament.

The use of argon in light bulbs prevents the evaporation of the tungsten filaments, which results in increased light bulb life.

Argon is also used to create an inert atmosphere for growing semiconductor crystals, arc welding and for processes that need protection from other kinds of atmospheric gases.

Learning is the knowledge of that which is not generally known to others, and which we can only derive at second­hand from books or other artificial sources. The knowledge of that which is before us, or about us, which appeals to our experience, passions, and pursuits, to the bosoms and businesses of men, is not learning. Learning is the knowledge of that which none but the learned know. He is the most learned man who knows the most of what is farthest removed from common life and actual observation. The learned man prides himself in the knowledge of names, and dates, not of men or things. He thinks and cares nothing about his next­door neighbours, but he is deeply read in the tribes and castes of the Hindoos and Calmuc Tartars. He can hardly find his way into the next street, though he is acquainted with the exact dimensions of Constantinople and Peking. He does not know whether his oldest acquaintance is a knave or a fool, but he can pronounce a pompous lecture on all the principal characters in history. He cannot tell whether an object is black or white, round or square, and yet he is a professed master of the optics and the rules of perspective.


Learning is defined as

A) the knowledge of that which is before us B) the knowledge about us
C) the knowledge of that which is not generally known to others D) the knowledge related to the businesses of men
 
Answer & Explanation Answer: C) the knowledge of that which is not generally known to others

The first working steam­ powered vehicle was designed and most likely built by Ferdinand Verbies, a Flemish member of a Jesuit mission in China around 1672. It was a 65 cm long scale­ model toy for the Chinese Emperor, that was unable to carry a driver or a passenger. It is not known if Verbiest's model was ever built. Nicolas- Joseph Cugnot is widely credited with building the first full­ scale, self ­propelled mechanical vehicle or automobile in about 1769; he also created a steam­ powered tricycle. He constructed two steam tractors for the French Army, one of which is preserved in the French National Conservatory of Arts and Crafts. His inventions were however handicapped by problems of water supply and maintaining steam pressure. In 1801, Richard Trevithick built and demonstrated his Puffing Devil road locomotive, believed by many to be the first demonstration of a steam ­powered road vehicle. It was unable to maintain sufficient steam pressure for long periods. Sentiment against steam ­powered road vehicles led to the Locomotive Acts of 1865. In 1807 Nicephore Niepce and his brother Claude probably created the world's first internal combustion engine which they called Pyreolophore.

The problem with Trevithick's Puffing Devil was:

A) Its incapability to carry a driver or a passenger B) With the water supply
C) Its inability to maintain steam pressure D) Its combustion engine
 
Answer & Explanation Answer: C) Its inability to maintain steam pressure
