The following is a feedback mechanism for a system :

<u>The progress bar when downloading a file on iTunes</u>

<u></u>

Explanation:

  • A feedback mechanism is a loop system wherein the system responds to a perturbation. The response may be in the same direction (as in positive feedback) or in the opposite direction (as in negative feedback).
  • Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself.
  • Evaluation feedback needs to be done “in the moment” to help the person receiving the feedback know where they stand.
  • A feedback control system consists of five basic components: (1) input, (2) process being controlled, (3) output, (4) sensing elements, and (5) controller and actuating devices.
  • Because negative feedback produces stable circuit responses, improves stability and increases the operating bandwidth of a given system, the majority of all control and feedback systems is degenerative reducing the effects of the gain.

A 3.52 kg steel ball is tossed upward from a height of 6.93 meters above the floor with a vertical velocity of 2.99 m/s. What is
Dafna1 [17]

Answer : The final velocity of the ball is, 12.03 m/s

Explanation :

By the 3rd equation of motion,

v^2-u^2=2as

where,

s = distance covered by the object = 6.93 m

u = initial velocity  = 2.99 m/s

v = final velocity = ?

a = acceleration = 9.8m/s^2

Now put all the given values in the above equation, we get the final velocity of the ball.

v^2-(2.99m/s)^2=2\times (9.8m/s^2)\times (6.93m)

v=12.03m/s

Thus, the final velocity of the ball is, 12.03 m/s

Suppose values is a sorted array of integers. Give pseudocode that describes how a new value can be inserted so that the resulti
Novosadov [1.4K]

Answer:

insert (array[] , value , currentsize , maxsize )

{

   if maxsize <=currentsize

  {

      return -1

  }

  index = currentsize-1

  while (i>=0 && array[index] > value)

  {

      array[index+1]=array[index]

      i=i-1

  }

 

  array[i+1]=value

  return 0

}

Explanation:

1: Check if array is already full, if it's full then no component may be inserted.

2: if array isn't full:

  • Check parts of the array ranging from last position of range towards initial range and determine position of that initial range that is smaller than the worth to be inserted.  
  • Right shift every component of the array once ranging from last position up to the position larger than the position at that smaller range was known.
  • assign new worth to the position that is next to the known position of initial smaller component.
