Q2086.General ScienceAsked in: NDA · NDA-II 2024, GATHard

Starting from rest a vehicle accelerates at the rate of 2 m/s² towards east for 10 s. It then stops suddenly. It then accelerates again at a rate of 4√2 m/s² for next 10 s towards south and then again comes to rest. The net displacement of the vehicle from the starting point is

  1. A.100 m
  2. B.200 m
  3. C.300 m
  4. D.400 m
Show answer
Correct answer: C. 300 m

The vehicle goes 100 m east and 200√2 m south, and the straight-line distance between start and finish is √(100² + (200√2)²) = 300 m. Each leg starts from rest, so the distance covered is s = ½at².

  2. B.ability to form a complex with haemoglobin
  3. C.ability to reduce some metal oxides
  4. D.property of having one sigma bond
Show answer
Correct answer: B. ability to form a complex with haemoglobin
