UHS MDCAT 2019 PAPER (PART 15) 1. Heavy nucleus of atoms go through fission so that they can: Absorb high amount of energy Reduce their binding energy per nucleon Absorb low amount of energy Increase their binding energy per nucleon 2. For projectile motion in the absence of air resistance: Vertical acceleration is zero Horizontal acceleration is zero Vertical speed is constant Horizontal force is constant 3. The range of the projectile depends upon the velocity of the projection and the angle of the projection i.e. 45°. For a fixed velocity, when the angle of projection is larger than 45°. Which of the following is correct? Both the height and the range attained by the projectile will be less The height attained by the projectile will be less but the range is more The height attained by the projectile will be more but the range is less. Both the height and the range attained by the projectile will be more 4. The wavelength of the electromagnetic wave having frequency of 3 kHz will be? 120 km 140 km 100 km 80 km 5.
