CHAPTER 1 - Pattern completion and correct options

Answers and solutions

5.1 OFFICIAL SUPR SAMPLE PAPER CHAPTER 1.Choose the correct alternative that will continue the same pattern and fillin the blank spaces.2,7, 14,23, ,47(b)31(c)38(d)27(e)None of these 2.It is postulated that huge deposits of NaCl (rock salt)and CaCO₃(chalk and marble)are sites oferstwhile oceans,where the salts had been concentrated through weathering by rain and wind andleaching by rivers.Select the correct explanatory statement in this context.(a)Both NaCl and CaCO₃are highly soluble in water. (b)NaCl is soluble in water but CaCO₃is not.Hence,concentration of CaCO₃in the oceans throughweathering is an untenable hypothesis. (c)The solubility of CaCO₃in water is pH dependent and is enhanced by acidic atmospheric gases.Hence,CaCO₃may be leached into water during weathering. (d)NaCl and CaCO₃are igneous rocks and have crystallized as such during the slow coolingprocess when the earth was born.Hence,the ocean postulates are baseless. 3.A known positive charge is located at point Pas shown above,between two unknown charges,Q1and Q2.P is closer to Q2 than Q1.If the net electric force acting on the charge at P is zero,it maycorrectly be concluded that:(A)Both Q1 and Q2 are positive(B)Both Q1 and Q2 are negative(C)Q1 and Q2 have opposite signs(D)Q1 and Q2 have the same sign,but magnitude of Q1 is greater than the magnitude of Q2 4.If log2=0.30103 and log3=0.4771,find the number of digits in(648)⁵.(a)23.(b)15.(c)13.(d)14.(e)22. 5.Which of the following solutions,when mixed,will not form a buffer solution?(a)100 mL 0.1 M NaOH+50 mL0.1 M CH₃COOH(b)50 ml 0.1 M NaOH+100 mL 0.1 M CH₃COOH(c)50 mL 0.1 M NH₄OH+50 mL 0.1 M CH₃COOH(d)50 ml 0.1 M HCI+100 mL0.1 M CH₃COONa 6.A man can cover a distance in 1hr 24min by covering 2/3 of the distance at 4km/h and the rest at5km/h.The total distance is(a)2km(b)5km(c)6km(d)10km(e)None of these 7.Three identical masses are at the three corners of the triangle,connected by massless identicalsprings(rest length 10)forming an isosceles right-angle triangle.If the two sides of equal length (oflength 2I0)lie along positive x-axis and positive y-axis,then the force on the mass that is not at theorigin but on the x-axis is given by ax^+by^with (a)a=1 and b=0 (b)a =0 and b=1 (c)a=-√2 and b=1 (d)a =-2 and b=0 (e)a=-2 and b=1 8.Asim got thrice as many sums wrong as he got right.If he attempted 60 sums in all,how manysums did he solve correctly?(a)25(b)12(c)20(d)10(e)15 9.A system consists of N particles,interacting with each other(for example,protein molecule).Whichone of the following statements is FALSE? (a)The motion of the system can be split into translational,rotational and vibrational motions(b)Number of rotational degrees of freedom are 3(c)Number or translational degrees of freedom are 3(d)Number of vibrational degrees of freedom are 3(e)The system,if isolated,will conserve both total energy and total angular momentum. 10.Three pipes A,B and C can fill a tank in 6 hrs.After working at it together for 2 hrs C is closed and Aand B can fill the remaining part in 7 hrs.The total number of hrs taken by C alone to fill the tank is(a)14(b)12(c)11(d)10(e)13 11.A square closed loop of area A,lying in the horizontal plane,is moving horizontally with velocity v ina uniform vertical magnetic field B.Which one of the following statements is FALSE?(a)There is current in the loop even though there is no battery(or any other voltage source)(b)The work done in moving the coil is being converted to the current in the coil(c)The current is being generated because the magnetic field is doing the work. (d)the emf generated is proportional to the velocity of the coil(e)the emf generated is proportionalto the magnetic field strength 12.Two liquids A and B are mixed in such a proportion that they form an ideal solution who's total vaporpressure is exactly three times that of the partial pressure of A.If PA and PB⁰are the vaporpressures of pure A an
