Answer:

3 Volts

Explanation:

Because Power = Voltage x Current, so if you substitute the values into the equation, it would be :

2.4 W = Voltage x 0.8 A

Then if you rearrange the equation, it would be :

2.4 W / 0.8 A = Voltage

Which is :

3 V = Voltage

What is key to remember when handling linked lists?

djyliett [7]

Answer:

Some key points to remember, when handling the linked list are as follow:

Linked list is the linear data structure in which each of the elements contain separate object.
Linked list components are not store in a contiguous location.
In the linked list the elements or components are basically use the pointers for linked with another elements.
The last node of the linked list must contain null value.
In the linked list, the allocation of the memory is equal to upper node limit.

What is the difference between front-end and back-end?

IgorLugansk [536]

Front-end the part with which the user interacts.

usually people who write this are called layout designers what languages are used (Html, css, js)

Beck-end The northern part is the structure of the site due to which it works, this includes the DBMS, logic, etc. which languages will be used(python, php, java)

People who can do both are called: full stack developr

Best case : 1.259

Bubble sort:

--------------------------------------------------------

Worst case : 1.990

Average case : 2.009.

Best case : 1.950

Explanation:

[NB: since it is very long there is the need for me to put it it a document form. Kindly check the doc. Files. The file A is the sort Analysis.Java file and the file B is the sort.Java file].

The concept of algorithm time measurement strictly depends on the following;

=> The measurement of time, space or energy on different sizes.

=> Plotting of the measurements and characterizing them.

=> Running or implementation of the algorithm.

Programming language such as Java can be used in accessing the operating system clock and Java had two static methods.
