The Answer Key:
Sr No Question Answer Remarks 1 The voltmeter and ammeter used for the measurement is having an error of 100 plus/minus 5 and 10 plus/minus 0.2 for voltmeter and ammeter respectively. These ammteres are used for the measurement of resistance, what error is expected? 7% During division and multiplication, the percentage errors are added. Percentage error of voltmeter is 5% and ammeter is 2% therefore, total is 7%. 2 A box weighing 1 Kg is lying on the floor of a vehicle having coefficient of friction 0.3. The vehicle acceleration in m/sec² shall be restricted to what level for the box to remain static? (g=10m/sec²) 3 The frictional force act in opposition to the acceleration equal to 1*10*0.3=3N. The force of acceleration shall never exceed 3 N for the box not to move. Therefore, acceleration shall be limited to 3/1 or 3 m/sec² 3 SI unit of surface tension is N/m There is general tendency to think that the unit of tension is N/m² where as it is N/m due to the tension prevailing at the line of interface between metal and liquid. In terms of energy it is also given as J/m². It is important to keep the formula on your sketch 4 Equation of continuity relates to the flow of liquid Equation of continuity is a statement f conservation of mass in flow of incompressible fluids and an important equation of Area*Velocity at any point in liquid flow remains constant. 5 Knowledge of Reynolds number is helpful in determining laminar or turbulent behaviour of fluid Osborne Reynolds number R =ρνd/η determines the tendency of fluid flow. When it is less than 1000, the flow is laminar and more than 2000, it is turbulent and between 1000 to 2000, it unsteady. 6 Sublimation is the process in which solid changes to gas directly The changes from solid state to vapour state without passing through the liquid state is called sublimation and the substance is aid to sublime. Dry Ice and Iodine are sublime substances. 7 Electron Microscope has to capability to measure least distances of the range of 1 Angstrom Electron Microscope of 0.6 A has been developed. The figures are generally given ascending or descending order. Sometime it is given at random. Don’t get influenced with the order. 8 60′ when converted into radian will be 0.0174 60′ is equal to 0° and equal to π/180° = 0.0174 radians. The distraction here is 60′ and there is possibility that one can go for the calculation of 1′ 9 Plastic materials are those which does not regains its original position after the applied force is removed Plastic material deforms and does not regain back its original position after the deformation force is removed. The material which regains it original position are called Elastic material. The distracter is that all the answers start with the language ‘ which does not or does regain’ and makes the candidate to confuse himself. 10 Two helical springs of spring constant k1 and k2 are attached with a mass in parallel, what will be total spring constant k=k1+k2 Spring constant behaves similar to capacitor for connection in parallel or series. when connected in parallel, the spring constant adds. Answer two is for when connected in series. -
