ETEA MDCAT 2022 PAPER MDCAT Paper (PART 8) 1. Which one is not a vector quantity? Angular displacement Moment of inertia Momentum Impulse 2. In Newton’s first law of motion which quantity remains constant Velocity Amount of work Angular displacement Amplitude 3. Law of inertia satisfies Condition of variable force Condition of force in contact Condition of conservation of mass Condition of equilibrium 4. When five times momentum of a body is equal to the kinetic energy of the same body then its velocity is equal to: 5 m/s 10 m/s 20 m/s 15 m/s 5. When angular speed of a body is doubled, the centripetal acceleration becomes: Four times remains the same Doubled Thrice 6. A projectile is launched, its velocity is maximum at: Highest point Between launching and highest point Point of projection All points 7. The equation for kinetic energy is: K.E=1/2mv.w K.E= 1/2mv.F K.E= 1/2mv.v K.E= P/2m 8. In an isolated thermodynamic system Neither heat nor any mass are transferred to the environment No mass transfers to the environment No heat transfers to the environment No dissipated energy and heat are transferred to the environment 9. The energy stored in a capacitor is given by: U= 1/2 QV^2 U= 1/2 CV^2 U= Q/2V U= 1/2 QC 10. Two bodies A and B of temperatures Ta= 100°C and Tp =0°C are brought in thermal contact with each other. Which one in the followings is possible at thermal equilibrium? TA = 60°C , TB= 50°C TA =0°C, TB = 100°C TA = 45°C , TB= 45°C TA = 60°C , TB= 40°C Loading … Pages: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
