What is the voltage drop across R4 in the diagram shown above?

R₂ and R₃ can be replaced by:

R_5 =  \frac{1}{\frac{1}{R_2} + \frac{1}{R_3}} = 106 \frac23

The total R of the circuit is R₁+R₅+R₄ = 706 2/3

So the current in the circuit I=V/R is 100/(706 2/3) = 15/106 A
(I'm deliberately not trying to round the result)

The voltage drop over R₄ is V=I*R = 15/106 * 500 ≈ 70

So answer C would be my choice.

You can use GitHub Pages! They have tutorials on their site to help you set up using that (too much for this format!). You can use it to make your own personal site, as well as host any existing site you may have.

"What is the running time of HEAPSORT on an array A of length n thatis already sorted in increasing order?
Harrizon [31]

Answer:

The answer to this question is O(NlogN).

Explanation:

The time complexity of Heap Sort on an array A is O(NLogN) even if the array  is already sorted in increasing order.Since the Heap Sort is implemented by creating the heap from the array and then heapifying and then repeatedly swapping first and last element and deleting the last element.The process will be done for the whole array.So the running time complexity is O(NLogN).

Assume that you have an array of integers named a. Which of these code segments print the same results?
Harrizon [31]

Answer: II and III only

The first code will print starting with the second variable in the array. So it will start with array[1] instead of starting with array[0]

The second code will start from array[0] as the variable i is 0. It will print the first value in the array before proceeding to increment the value of i.

The third code will also start from array{0] as the program will check for the first value of a before proceeding to the next one.

An example would be if we were to define the array as:

int[] a = {1,2,3,4,5};

1st Code Output:

2

3

4

5

2nd Code Output:

1

2

3

4

5

3rd code Output:

1

2

3

4

5

Always remember that arrays will always begin from 0.

Consider the following program written in C syntax:
postnew [5]

The values of the variables value and list after each of the three calls to

swap are:

  • value = 2 and  list[5] = {1, 3, 5, 7, 9};
  • value = 2 and  list[5] = {3, 1, 5, 7, 9};
  • value = 2 and  list[5] = {3, 1, 5, 7, 9};

<h3>How to determine the values of variable value and the list?</h3>

<u>1. Passed by value</u>

In this case, the values of the actual arguments remain unchanged; So the variable value and the list would retain their initial values

The end result is:

value = 2 and  list[5] = {1, 3, 5, 7, 9};

<u>2. Passed by reference</u>

With pass by reference, the arguments are changed.

Given that

value = 2 and  list[5] = {1, 3, 5, 7, 9};

The value of variable value is swapped with list[0].

So, we have:

value = 1 and  list[5] = {2, 3, 5, 7, 9};

Then list[0] and list[1] are swapped

So, we have:

value = 1 and  list[5] = {3, 2, 5, 7, 9};

Lastly, value and list[value] are swapped

So, we have:

value = 2 and  list[5] = {3, 1, 5, 7, 9};

The end result is:

value = 2 and  list[5] = {3, 1, 5, 7, 9};

<u>3. Passed by value-result</u>

Since there is no loop in the program, the pass by value-result has the same output as the pass by reference.

So, the end result is:

value = 2 and  list[5] = {3, 1, 5, 7, 9};
