Answer:

i. Damage of Power adapters that are supplying power from the switch to the computer.

ii. Damage/ Failure of power supply inside the computer.

Explanation:

There could be many possible reasons that computer is not working or power up while pressing power button. Two of them are discussed here.

i. If the power adapters or cords are damaged than computer will not switched on or display or sound any thing on the computer. As power is not reached to computer with the help of cords. In that case just check that, power cords are perfectly installed in computer and power plugs and that are not damaged.

ii. In case computer power supply is damaged then the computer system will not switched on any nothing will be displayed on the screen. The power supply should be replaced.

iii. In case of memory failure the computer will not start.

iv. In case there is power supply to processor fan damaged than computer will not switched on.

Define and implement a method that takes a string array as a parameter and returns the length of the shortest and the longest st
Drupady [299]

Answer:

#HERE IS CODE IN PYTHON

#function to find length of shortest and longest string in the array

def fun(list2):

   #find length of shortest string

   mn=len(min(list2))

   #find length of longest string

   mx=len(max(list2))

   #return both the value

   return mn,mx

#array of strings

list2 = ['Ford', 'Volvo', 'BMW', 'MARUTI','TATA']

# call the function

mn,mx=fun(list2)

#print the result

print("shortest length is:",mn)

print("longest length is:",mx)

Explanation:

Create an array of strings.Call the function fun() with array as parameter. Here min() function will find the minimum string among all the strings of array and then len() function will find its length and assign to "mn". Similarly max() will find the largest string and then len() will find its length and assign to "mx". Function fun() will return "mn" & "mx".Then print the length of shortest and longest string.

Output:

shortest length is: 3

longest length is: 5

Consider the partially-filled array named a. What does the following loop do? (cin is a Scanner object)int[] a = {1, 3, 7, 0, 0,
boyakko [2]

Answer:

Option 1: May crash at runtime because it can input more elements than the array can hold

Explanation:

Given the code as follows:

  1.        int[] a = {1, 3, 7, 0, 0, 0};
  2.        int size = 3, capacity = 6;
  3.        int value = cin.nextInt();
  4.        while (value > 0)
  5.        {
  6.            a[size] = value;
  7.            size++;
  8.            value = cin.nextInt();
  9.        }

From the code above, we know the <em>a</em> is an array with six elements (Line 1). Since the array has been initialized with six elements, the capacity of the array cannot be altered in later stage.

However, a while loop is created to keep prompting for user input an integer and overwrite the value in the array started from index 3 (Line 4- 9). In every round of loop, the index is incremented by 1 (Line 7). If the user input for variable <em>value</em> is always above zero, the while loop will persist.  This may reach a point where the index value is out of bound and crash the program. Please note the maximum index value for the array is supposedly be 5.

Eq-20 why is the height of a vhf radio antenna important
masya89 [10]
Reasons why the height of a VHF radio antenna is important is because VHF radios work by the line of sight principle.
Line of sight
its a line from observers eye to a distant point.its a line between two points specifically the straight path between a transmitting antenna (as for radio or television signals) and receiving antenna when unobstructed by the horizon.

Imagine you had a learning problem with an instance space of points on the plane and a target function that you knew took the fo
gavmur [86]

Answer:

The answer is nearest-neighbor learning.

because nearest neighbor learning is classification algorithm.

It is used to identify the sample points that are separated into different classes and to predict that the new sample point belongs to which class.

it classify the new sample point based on the distance.

for example if there are two sample points say square and circle and we assume some center point initially for square and circle and all the other points are added to the either square or circle cluster based on the distance between sample point and center point.

while the goal of decision tree is to predict the value of the target variable by learning some rules that are inferred from the features.

In decision tree training data set is given and we need to predict output of the target variable.
