Q:

For an ideal gas, which one of the following statements does not hold true?

A) The speed of all gas molecules is same B) The kinetic energies of all gas molecules are not same
C) The potential energy of the gas molecules is zero D) There is no interactive force between the molecules.
 
Answer & Explanation Answer: A) The speed of all gas molecules is same

Explanation:

In an ideal gas, at any particular time, different particles in the gas have different speeds and hence different kinetic energies. This assumption is reasonable because as the particles collide, we expect their speed to change. Even if initial speed of all the particles was same, the molecular collisions will disrupt this uniformity.Hence statement 1 is incorrect and 2 is correct.

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.

Cugnot built steam tractors for:

A) The Chinese Emperor B) The French Army
C) The Jesuit mission D) The French Conservatory

Q:

Differ between static and dynamic RAM?

Answer

Static RAM: no refreshing, 6 to 8 MOS transistors are required to form one memory cell, information stored as voltage level in flip flop. 


Dynamic RAM: refreshed periodically, 3 to 4 transistors are required to form one memory cell, information is  stored as a charge in the gate to substrate capacitance.
