Question Solved1 Answer The following processes are being scheduled using a preemptive, priority-based, round-robin scheduling algorithm. Process Burst Time Priority. Arrival P1 8 15 0 P2 3 20 o P3 4 20 20 P4 4 20 25 5 5 45 P5 P6 5 15 55 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. a. Show the scheduling order of the processes using a Gantt chart. b. What is the turnaround time for each process? c. What is the waiting time for each process? d. What is the average waiting time?

Search the Web for security education and training programs in your area. Keep a list and see which category has the most examples. See if you can determine the costs associated with each example. Which do you think would be more cost-effective in terms of both time and money?

(a) Use the definition given below with right endpoints to express the area under the curve y = x3 from 0 to 1 as a limit. = The area A of the region S that is bounded above by the graph of a continuous function y = f(x), below by the x-axis, and on the sides by the lines x = a and x = b is the limit of the sum of the areas of approximating rectangles. n lim Rn A = n00 lim [f(x4)Ax + f(x2)4x + = + f(x,)Ax] = lim. į f(x;)Ax n00 i=1 n lim n00 i = 1 (b) Use the following formula for the sum of cubes of the first n integers to evaluate the limit in part (a). 12 13 + 23 + 33 + ..-( ) 3 = n(n + 1) 2

A planet of mass 3 x 1024 kg is at location (5 x 1011, -5 x 1011, 0) m. A star of mass 3 x 1030 kg is at location (-5 x 1011, 4 x 1011, 0) m. It will be useful to draw a diagram of the situation, including the relevant vectors. (a) What is the relative position vector r pointing from the planet to the star? r= m (b) What is the distance between the planet and the star? Irl m (c) What is the unit vector in the direction of r? (d) What is the magnitude of the force exerted on the planet by the star? |Fon planet| = N (e) What is the magnitude of the force exerted on the star by the planet? |Fon star] = N (f) What is the force (vector) exerted on the planet by the star? (Note the change in units.) Fon planet = x 1020 N (g) What is the force (vector) exerted on the star by the planet? (Note the change in units.) Fon star = x 1020 N

JAVA write 2 classes : CashRegister.java and CashRegisterTester.java a cashRegister should have 3 instance variables:- itemCount that represents the numbers of items bought, totalPrice that represents the total price of all your items, and itemNames that represents a concatenated string of the names of all the products you bought. The CashRegister should

Consider the following reaction: A + 2B → E Using steady-state approximation determine which of the following can determine the overall rate law (assume that the rate determining step is unknown), if the reaction mechanism consists of the following elementary steps: 1. A + B → 2C (rate constants: k1 for forward reaction; k2 for reverse reaction) 2. 2C + B → E (rate constant: k3) Question 4 options: a) k3[B][C]2 b) (k3k1[A]2[B])/(k2+k3[A]) c) (k3k1[A][B]2)/(k3-k2[B]) d) (k3k1[A][B]2)/(k2+k3[B]) e) (k3k1[A][B]2)/(k3+k2[B])

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 14.5 mm. In this configuration, q1 exerts a repulsive force of 2.62 µN on q2. Particle q2 is then moved to x2 = 18.6 mm. What is the force (magnitude and direction) that q2 exerts on q1 at this new location? (Give the magnitude in µN.) magnitude µN direction −î 6.
