In doing a load of clothes, a clothes drier uses 18 A of current at 240 V for 59 min. A personal computer, in contrast, uses 3.0

A of current at 120 V. With the energy used by the clothes drier, how long (in hours) could you use this computer to "surf" the Internet?

Answer:

11.76 hours or 11 hours 45 minutes

Explanation:

Given

Current\ for\ drier = I_d = 18A\\Voltage\ for\ drier=V_d=240V\\Time\ for\ drier=t_d=59\ min

We have to convert minutes into hours

So,

t=\frac{59}{60} = 0.98\ hours

Current\ for\ Computer=I_c=3.0A\\Voltage\ for\ computer=V_c=120V

As we are given that we have to find the time the computer will sustain using the same energy as the drier. So,

I_d*V_d*t_d=I_c*V_c*t_c\\18*240*0.98=3*120*t_c\\t_c*360=4233.6\\t_c=\frac{4233.6}{360}\\ t_c=11.76\ hours

<u>Converting into minutes will give us: 11 hours 45 minutes </u>

Therefore, with the same energy used by the drier, the computer can be used 11.76 hours to surf the internet ..

When creating a multi-dimensional array dynamically in C/C++ the Memory Manager will go to great pains to make sure the array is
yuradex [85]

Answer:

Here the statement is false.  

Explanation:

In C/C++, we can define multidimensional arrays in simple words as an array of arrays. Data in multidimensional arrays are stored in tabular form (in row-major order).  

General form of declaring N-dimensional arrays:  

data_type  array_name[size1][size2]....[sizeN];  

data_type: Type of data to be stored in the array.  

          Here data_type is valid C/C++ data type

array_name: Name of the array

size1, size2,... ,sizeN: Sizes of the dimensions.

Foe example:

Two dimensional array:

int two_d[10][20];  

Three dimensional array:

int three_d[10][20][30];

zhannawk [14.2K]

Answer:

3 parameters are passed into the function.

1 value will be returned from the function.

Explanation:

From the function definition "function sum(first, second, third)", we can see  that there are three value/parameters are passed in the function.Then variable "result" will be the sum all the three values. After that it will print the all three values in new line. Then the function will return one value which is the  sum of all three that is value of "result".As there is only one value returned  by the return statement in the function.

Show the steps of a Selection Sort for the numbers ( 5 3 9 5 ).
Sedbober [7]

Answer:

Sorted array will be:-

3 5 5 9

Explanation:

In Selection Sort algorithm it sorts the array by repeatedly finds the minimum in the array form the array that is unsorted and swaps it with the value at the first position.

The unsorted array:- 5 3 9 5

In first iteration

minimum is 3.

3 will be swapped with 5.

Now the array is 3 5 9 5

sorted array 3

In second iteration

unsorted array is 5 9 5

sorted array 3 5

and the minimum from it is 5

No swapping will occur.

In third iteration

unsorted array is 9 5

minimum is 5

sorted array 3 5 5

swap it with 9.

Now the array is sorted.

3 5 5 9
