Statement-2: NOT gate inverts the input order.

  • A
    Statement -1 is false, statement -2 is true.
  • B
    Statement 1-is true, statement -2 is true and statement -2 is correct explanation of statement-1.
  • C
    Statement 1-is true, statement -2 is true but statement -2 is not correct explanation of statement-1.
  • D
    Statement 1-is true, statement -2 is false.
✓

Answer

  1. Statement 1-is true, statement -2 is true and statement -2 is correct explanation of statement-1.

Explanation:

NOT gate is also called invertor circuit since NOT gate inverts the input order. Hence, statement 1-is true statement-2 is true statement-2 is correct explanation of statement-1.

Free 238U nuclei kept in a train emit alpha particles. When the train is stationary and a uranium nucleus decays, a passenger measures that the separation between the alpha particle and the recoiling nucleus becomes x in time t after the decay. If a decay takes place when the train is moving at a uniform speed v, the distance between the alpha particle and the recoiling nucleus at a time t after the decay, as measured by the passenger will be:
  1. x + vt
  2. x - vt
  3. x
  4. depends on the direction of the train.
