Sindh MDCAT 2018 paper MDCAT 2018 paper ( PART 5 ) 1. If a dielectric material is placed between two plates of a capacitor, the net capacitance of the capacitor: Decreases Remains constant Zero Increases 2. Let X be a radioactive element having N nuclei. TNN time required to decay this element to one half of its initial number N is known as: Law of radioactive decay Decay Time Decay constant Half life 3. When an electron and its anti-particle positron come close enough to each other, they completely convert into radiation energy in the form of photons, this process is called: Pair production Compton effect Annihilation of matter Photo electric effect 4. Which of the following phenomenon represents the wave nature of light? Pair production Photoelectric effect Compton scattering Interference of light 5. which process is shown in the graph between pressure and volume ? Adiabatic Isochoric Isobaric Isothermal 6. Equations of kinetics are valid only when the acceleration is: Constant Increasing Decreasing Vary with time 7. In simple harmonic motion, a particle is oscillating in such a way that its total energy remains conserved. When this particle reaches its two extreme positions, its potential energy at extreme positions becomes: Zero Maximum Greater than its kinetic energy Minimum 8. If current is flowing through a coil then flux through coil will become constant. In such typireboef arrangement the electro motive force end induced in coil wil : Self-inductance Mutual-inductance Zero Back emf 9. Law of heat exchange is used determine: Specific heat of substance Coefficient of volume expansion Ideal gas constant Coefficient or linear expansion 10. If a car collides with a housefly, what will he the magnitude of the force experienced by the housefly? Much lesser than the car experienced by the housefly 10 times less than the car experienced by the housefly Same as the car experienced by the housefly Much greater than the car experienced by the housefly Loading … Pages: 1 2 3 4 5 6 7 8 9 10
