NDA/NA SOLVED PAPER 2016-I (GENERAL KNOWLEDGE)Total Questions: 10061. Which one of the following carbon compounds will not give a sooty flame?(a) Benzene(b) Hexane(c) Naphthalene(d) AnthraceneCorrect Answer: (b) HexaneSolution:Hexane do not give sooty flame as it is alkane and saturated compound where as Benzene, Naphthalene and Anthracene are aromatic and unsaturated so they give sooty flame.62.

In Thar region, the shifting sand dunes are locally known as(a) Dhrian(b) Daurs(c) Dhoros(d) DhayaCorrect Answer: (a) DhrianSolution:In Thar desert the shifting sand dunes are locally known as Dhrian.64. The impulse on a particle due to a force acting on it during a given time interval is equal to the change in its(a) force(b) momentum(c) work done(d) energyCorrect Answer: (b) momentumSolution:The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it.65. Which one of the following statements with regard to expansion of materials due to heating is not correct?(a) As ice melts, it expands uniformly up to 4°C.(b) Mercury thermometer works using the principle of expansion due to heating.(c) Small gap is kept between two rails to allow for expansion due to heating.(d) The length of metallic wire increases when its temperature is increased.Correct Answer: (a) As ice melts, it expands uniformly up to 4°C.Solution:Most solids expand when heated and contract when cooled. Water/ice is anomalous in that it expands when cooled, at least near its freezing point.66. Which of the following pairs is/are correctly matched?(National Park)(Famous for)1. RanthambhoreTiger2. PeriyarElephant3. ManasLion4. GirRhinocerosSelect the correct answer using the code given below:(a) 1, 2 and 3 only(b) 1 and 2 only(c) 1 and 4 only(d) 2 onlyCorrect Answer: (b) 1 and 2 onlySolution:Ranthambore national park is famous for Tigers, Periyar national park is famous for elephant, Manas Sanctuary is famous for Rhinoceros and Gir forest is famous for lion.67. Which one of the following is not a form of stored energy?(a) Nuclear energy(b) Potential energy(c) Electrical energy(d) Chemical energyCorrect Answer: (c) Electrical energySolution:Nuclear potential and chemical energies implies the stored form of energy. But electrical energy is not a form of stored energy.68. The motion of a car along a straight path is shown by the following figureThe car starts O and reaches at A, B and C at different instants of time. During its motion from O to C and back to B, the distance covered and the magnitude of the displacement are, respectively(a) 25 km and 60 km(b) 95 km and 35 km(c) 60 km and 25 km(d) 85 km and 35 kmCorrect Answer: (d) 85 km and 35 kmSolution:Distance covered by the car = OA + AB + BC + CB = 25 + 10 + 25 + 25 = 85Km Displacement by the car = OB = 35Km69.
