Re: Special Class Railway Apprentices Exam Physical Sciences papers
Here I am giving you question paper for Special Class Railway Apprentices Examination of Physical Sciences in a PDF file attached with it so you can get it easily. A particle moves rectilinearly with retardation a whose magnitude is dependent of velocity as a = b& where 'b' 'is a positive constant. The initial ' velocity of the particle is v,,. How long will the pairtick move before coming to rest ? A modei of solar system is scded down in the ratio 'k' but of materials of safne mean density and actual materials of the planets and the sun. What happens to orbita3 periods- of revolution of the planetary models ? (a) The orbital period of revolution does not change (b) The drbital period of revolution increases by a factor 'k' , . (c) The orbital period of revolution. - dlecrcases by a fkctor 'k' (d) Data insufficient to draw the conclusion A pulse of the form y = aeax2 is formed on a rope. Which one of the following functions represknts the pulse travelling at 1.0 d s in the negative x-direction ? (4 Y = ,*x-l ott2 (W Y = e(4x"' ot) (=) y = ae*x+lwZ 2 (4 Y = &bx -101) 2 - 4. The ultimate limit of resolution of an optical microscope is set by : (a) aberrations (b) length of microscope tube . . (c) design of objective lens (d) diffraction of light .5. 8 g of oxygen and 7 g of nitrogen are mixed in a container. What is the value . of 'n' in the expression PV = nRT of this mixture ? (a) i/4 (b) 112 (4 2 - (d) 15 6. The ear. piece of a telephone is made of material having : (a) large hysteresis and high permeability (b) low hysteresis and large retentivity .(c) high permeability and low eddy cumnt only (d) low.hysteresis, low eddy current and high permeability 7. A wire of length L is pIaced parallel to the lines of force in a uniform magnetic field B. If I is the current in the wire, ' then it will experience : (a) a force in the direction of magnetic field (b) a force in the direction opposite to the direction of magnetic field (c) a force. in the direction perpendicular to the direction of magnetic field (d) no force SCRA Physical Sciences paper |
