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 Increases Remains constant Zero 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: Decay Time Law of radioactive decay 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: Photo electric effect Annihilation of matter Pair production Compton effect 4. Which of the following phenomenon represents the wave nature of light? Photoelectric effect Compton scattering Pair production Interference of light 5. which process is shown in the graph between pressure and volume ? Isobaric Isochoric Isothermal Adiabatic 6. Equations of kinetics are valid only when the acceleration is: Constant Decreasing Vary with time Increasing 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: Minimum Maximum Greater than its kinetic energy Zero 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 : Back emf Mutual-inductance Zero Self-inductance 9. Law of heat exchange is used determine: Ideal gas constant Specific heat of substance Coefficient or linear expansion Coefficient of volume 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 Much greater than the car experienced by the housefly Same as the car experienced by the housefly 10 times less than the car experienced by the housefly Loading … Pages: 1 2 3 4 5 6 7 8 9 10
