A sheet of paper is placed on a table and a jug full of water is kept on it while pulling the paper suddenly, it is observed that the water does not spill out of the jug. It is due to the inertia of the paper sheet jug & water in it jug table2. The value of plank’s Constant depends upon frequency is always same depends upon energy depends on wavelength 3. Doping is a process of purifying the semiconductor making the material crystalline adding controlled impurities into the material making the material an insulator 4. A sample of gas is at 0°C. What is the requirement of increase in temperature to double the r.m.s. speed of molecules ? 273°C 1000°C 373°C 500°C5. If there is no atmosphere, then the duration of daylight on earth will Increases Decreases Remains Same Can not be ascertained6. A fuse wires has eventially High resistance & high melting point Low resistance & high melting point Low resistance & low melting point High Resistance & low melting point7. The acceleration due to gravity is zero at Poles Equator Centre of Earth it Can not be zero8. Pascal’s law hold good for Gases only Liquid and fluids only Solids only for all 9. When white light is passed through a prism, it is observed that violet light bends more than the red light. This is because Velocity of red light in glass is less than that of violet light Refractive Index of glass is more for violet light wave length of violet light is less than that of red light It is the properties of these colours. 10. An engine supplies 196 joules of energy. If the energy is supplied to a weight of 500 gms. How much height can the weight attain? 38.2 m 39.2 m 40.2 m 41.2 m11. Find at what temperature, the velocity of sound in air is 1.5 times the velocity at 700 °C 357 °C 387 °C 350 °C 373 °C12. A person using convex lense must be suffering from Myopia Astigmatism Hypermyopia Can not be ascertained13. The critical angle of liquid is 30°. Its refractive Index will be 4 3 0.5 214. A hygrometer measures The constant of Hydroscopic substance Relataive density of solids Relative density of liquids Amount of water vapour in air 15. One weber/m2 is equal to (A) 10-3 gram (B) 10-4 gram (C) 104 gram A B C NoneYou can always contact system administrator here for any kind of technical glitches. 1Utkarsh Gupta likes this.
