NUMS MDCAT 2024 PAPER NUMS 2024 ( PART 11 ) 1. A particle moves in a circle of radius 200cm with a linear speed of 20 m/s. Find the angular velocity: 20 rad s-1 200 rad s-1 10 rad s-1 2 rad s-1 2. For anti clock wise rotation the angular displacement is: Negative Null Zero Positive 3. Speed of sound in solid Is grantor than speed of sound in air because ratio: C B A D 4. A body of mass 10 kg is connected to a spring and it Is oscillating on a horizontal frictionless surface. If the maximum displacement of body Is 20 cm and spring constant Is 20 Nm-1. What is the acceleration of the body 2.2 ms-2 4 ms-2 2 ms-2 0.4 ms-2 5. A normal person can hear sound waves ranging In frequency from 20Hz to 20KHz. The maximum wavelength is: 17km 17cm 17mm 17m 6. NaCl dissolves quickly in water due to : Er = 0 High Er Low Er Er = ∞ 7. A capacitor can be fully charge because time required to charge is: Infinity 4 time constant 2 time constant 1 time constant 8. The electric field at distance of 10cm from a 2µc point charge is: 180 C 180 × 10⁶ N/C 1.8 × 10⁶ N/C 1.8 C 9. At midpoint P: V=0, E≠0 v≠0, E=0 V=0, E=0 v≠0, E≠0 10. A process in which all the heat energy is used for increasing internal energy of the system is known as: Isochoric Adiabatic Isothermal Isobaric Loading … Pages: 1 2 3 4 5 6 7 8 9 10 11 12
