SINDH RECONDUCTED MDCAT 2024 PART 6 1. The boiling point of water in Kelvin scale is: 273K 373K 32K 0 K 2. 1 Atomic Mass Unit is equal to: 1.66×10 × -28 g Equal to mass of electron 1.66×10 × -24 kg Mass of one atom of H 3. The average distance covered by the gas molecule between successive collisions is known as: Mean free path Total free path Total path Free path 4. The gas law in which the pressure is kept constant is known as: Graham’s Law Charles Law Dalton’s Law Boyle’s Law 5. The pressure 14.7 psi is equal to: 1 Nm 1 atm 1 torr 1 pascal 6. The Magnetic quantum number of 4f orbital would be: -2,-3,-1 0, +2, +3, +1,4 -3,-2,-1,0,1,2,3 -3,-4,-2,-1,0,+4,+3,+2,1 -2,-3, -1 0, +2, +3, +1 7. A magnetic field exerts a force on a charged particle: If the particle moving across the field lines If the particle is at rest If the particle moving along the field lines Always experience force 8. When magnetic field and area vector are perpendicular then magnetic flux will be: Minimum Zero Maximum Optimum 9. A coil of 600 turns is threaded by magnetic flux of 8 webers. If this flux is reduced to 5 webers in 3 seconds. The induced EMF in the coil will be: 900V 600V 800V 700V 10. A generator supplies 100 V to the primary coil of a transformer. The primary has 150 turns and the secondary has 500 turns. The secondary voltage is: 700V 900V 800V 1000V Loading … Pages: 1 2 3 4 5 6 7 8 9
