Mock drill is necessary to check your preparation at intervals to take corrective action in time before it is too late. Here are series of mock drill questions as per the syllabus prescribed for the forthcoming examination by RRB for the recruitment of SSE/JE.

This is a set of multiple choice questions as per the syllabus of SSE/JE examination 2015

21	Avogadro number is a fixed number equal to 6.022*1023 defines the number of moles of what in 1 mole of any substance	all	The number of particles i.e. atom, molecules or ions present in 1 mole of any substance is fixed, with a value of 6.022*1023. This is an experimentally obtained value and called Avogadro Constant. The mass of 1 mole of a particular substance is always constant. It is equal to sum total of relative masses of atoms or molecules in grams.
22	In Tungston Inert Gas called TIG welding process, the consumable material is	Separate filler material	Tungston is only an electrode to sustain the arc and filler material is used continously to fill the gap
23	Weight of 1 kg mass is	1 Kg	Unit of mass is Kilogram and same is taken for the weight. It is in Physics, that it is taken as the force of attraction due to gravity and is Mg equal to 1 Newton. Newton is the unit of force.

25	What is a tissue?	A groups of cells which is meant for a specific task is called tissue	Tissue and Division of Labour: In complex organisms, different tasks are carried out by different organs and organ systems. Tissues are the first step towards division of labour in complex organisms. A groups of cells which is meant for a specific task is called tissue.
26	Each living cell has got a certain specific components within it called	organelle
27	The US president who served only one term of 4 years in the office	George H W Bush
28	Resistive Welding process involves use of	clamping of two surfaces and passage of high current which melts the two surfaces and their welding	The advantages of the method include efficient energy use, limited workpiece deformation, high production rates, easy automation, and no required filler materials. Weld strength is significantly lower than with other welding methods, making the process suitable for only certain applications. It is used extensively in the automotive industry—ordinary cars can have several thousand spot welds made by industrial robots. A specialized process, called shot welding, can be used to spot weld stainless steel.
29	Precision of a measuring device tells about	the degree of freedom from random error	There are four characteristics of errors in measurement termed as Precision, Accuracy, Repeatability and Reproducibility having different application. Accuracy: The accuracy of an instrument is a measure of how close the output reading of the instrument is to the correct value. In practice it is quoted in terms of inaccuracy percentage on the measured value. Precision: It is a term that describes an instrument’s degree of freedom from random errors. If a large number of readings are taken of the same quantity by a high precision instrument, then the spread of readings will be very small. Repeatability: It describes the closeness of output readings when the same input is applied repetitively over a short period of time keeping all measurement conditions, instrument, observer, location and use similar. Reproducibility: It describes the closeness of output readings for the same input when there are changes in the method of measurement, observer, measuring instrument, location, conditions of use and time of measurement.

However, in actual practice some acceleration is required to compensate the retarding force arising out due to surface/air friction.
32	Plant tissues are of two types of which one is Meristematic and what is the second one?	Permanent Tissue	Plant tissues are of two main types, viz. meristematic tissue and permanent tissue. The distracters mentioned are types of meristematic type of tissue.

39	First emission norms were introduced for petrol Engine in the year	1991
40	The SI unit of large weight of a body is	Newton	Weight is the gravitational force acting on a body and is determined as m*g with unit as that of force i.e. Newton. SI unit of mass is Kg. The weight of a body remains constant throughout on earth as g is constant, meaning thereby that W is proportional to m and for this reason, weight is used commonly for mass.
41	First emission norms were introduced for Diesel Engine in the year	1992
42	The work done in lifting 1 Kg of mass for a distance of 1 m is equal to	9.81 Joules	The force acting on the body down ward is 1 Kgg=9.81 N and the work done is FS=9.81 N-m or Joule
43	Where was the capital of Chandra Gupta Maurya established?	Patliputra
44	Number of Railway stations in Indian Railways are in the range of	7000
45	Fill the blank in the series : B2CD, _____, BCD4, B5CD, BC6D	BC3D
46	How to use 5A (AC) rated moving iron ammeter to measure 1000 A (AC) current?	Using current transformer	For measurement applications in High power sub-stations, the current and voltages are very high and shunt or series resistance cannot work. Current and Potential transformers are used to reduce the level to its operating level of the instrument.
47	What are the essential property of an item to be called a matter	is made up of particle which has has mass, volume, space, force between them and energy
48	The disease not caused by virus is	tuberculosis	The disease caused by virus is one in which the virus dies by itself and no medicine services the purpose.
49	This is not a conventional abrasives used in grinding wheel	Cubic Boron Nitride	Cubic Boron Nitride and Diamond are superabrasive and non-conventional for specific application. For more details visit http://www.mmsonline.com/articles/choosing-the-right-grinding-wheel
