A bomb of mass 30 kg at rest explodes into two pieces of masses 18 kg and 12 kg. The velocity of 18 kg mass is 6 m/s. The kinetic energy of the other mass is__

18. Recall that in a Round Robin CPU scheduling each process takes turn and runs for a specified time slice. Assume 3 processes are in ready states with required service times in seconds) as indicated in the following table. Assume also that allowed time slice is 10 seconds. What is the turn-around time for process P2? Process Service Time P1 25 P2 30 To a) 30 b) 55 c) 75 x d) 100 e) None of the above

18. How many times does the letter B print in the following code? for (int i = 0; i < 6; i++) { for (int j = 0; j <= 5; j++) System.out.println("B"); { (A) 36 (B) 5 (C) 0 (D) 30 (E) 11
