Q:

Which  one  of  the  following  statements  is not correct?

A) The    cathode    rays    originate    from cathode   and   proceed   towards   the anode   in   a   cathode-ray   discharge tube. B) The television picture tubes are nothing but cathode ray tubes.
C) The  cathode  rays  themselves  are  not visible. D) The   characteristics   of   cathode   rays depend  upon  the  nature  of  the  gas present in the cathode-ray tube.
 
Answer & Explanation Answer: D) The   characteristics   of   cathode   rays depend  upon  the  nature  of  the  gas present in the cathode-ray tube.

Explanation:

Cathode ray is a beam of electrons emitted   from   the   cathode   of   a vacuum    tube.    It    is    invisible. Cathode  ray  tubes  are  also  found in     televisions     and     computer monitors.  Since  cathode  ray  is  a beam of electrons and all electrons are  identical,  charge  to  mass  ratio is same for all the gases and does not depend on the nature of gas.

Read the passage carefully and choose the best answer to each question out of the four alternatives and click the button corresponding to it.

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 Pyreolophore was ?

A) A self­propelled mechanical vehicle B) A steam-­powered tricycle
C) A steam tractor D) The name of the world's first internal combustion engine
 
Answer & Explanation Answer: D) The name of the world's first internal combustion engine
