Question 5

The following processes are being scheduled using a preemptive, priority-based, round-robin scheduling algorithm. Each process is assigned a numerical priority,with a higher number indicating a higher relative priority. The scheduler will execute the highest-priority process. For processes with the same priority, a round-robin scheduler will be used with a time quantum of 10 units. If a process is preempted by a higher-priority process, the preempted process is placed at the end of the queue.

Process          Burst Time      Arrival Time   Priority

P1                15            0            8

P2                20           0            3

P3                20           20           4

P4                20           25           4

P5                5            45           5

P6                15            55           5

There are n processes in a queue. Each process has namei and timei. The round-robin scheduling handles the processes in order. A round-robin scheduler gives each process a quantum (a time slot) and interrupts the process if it is not completed by then. The process is resumed and moved to the end of the queue, then the scheduler handles the next process in the queue. For example, we have the following queue with the quantum of 100ms. A(150) - B(80)...

For each of the following processes, describe what kind of energy is being converted into what other kind(s). Valid forms of energy for the purpose of this question are “kinetic energy of (object),” “gravitational potential energy,” “elastic potential energy of (object),” or “internal energy of (object).” There may be more than one conversion involved, so your answer should be a kind of narration of the energy conversion(s). For example, if the process is, “A girl skating on rollerblades skids to...
