SZABMU MDCAT 2024 PAPER SZABMU RECONDUCTED PAPER ( PART-2 ) 1. In SHM, α — x , the negative sign indicates that: Acceleration is directed towards equilibrium Acceleration is decreasing Acceleration is zero at extreme position Acceleration is directed away from equilibrium 2. In moist air (humidity), the speed of sound wave: Zero Decreases Increases Remain same 3. The temperature of air is increased 1°C than increase in speed of sound is; 0.61 ms*-1 6.1 ms*-1 1.6 ms*-1 0.16 ms*-1 4. A wave generator produces 100 pulses in 10s. Then the frequency of pulse it produces will be 100 Pulses s-1 1 Pulses s-1 10 Pulses s-1 0 Pulses s-1 5. When an object starts from rest, then first equation of motion is given as: vf= at vf= Vi – at vf= vi + 1/2 at vf=√at 6. Acceleration of Light travelling in vacuum: 3 x 10*10 cm/s*2 Zero 299792458 m/s*2 1,86000 miles/s*2 7. Ignoring air resistance, Acceleration of the projectile is: 10 m/s*2 vertically downward 10 m/s*2 Horizontally 10 m/s*2 vertically upward Zero 8. Two bodies having same mass undergo elastic collision then their velocities after collision will be: v1* = v2 V2*= 0 v1* = v2 V2*= v1 v1* = 0 V2*= v1 v1* = v1 V2*= v2 9. Momentum is product of mass and velocity then momentum and Velocity are: Parallel Perpendicular Antiparallel Independent 10. The angle between velocity and acceleration at maximum height is: 180° 90° 60° 0° Loading … Pages: 1 2 3 4 5 6
