Answer:

The element is positioned according to the normal flow of the document.

The top, right, bottom, left, and z-index properties have no effect. This is the default value.

The behavior of an element with static positioning in regard to the page layout is that it implies that one put the element in its original position in the aspect of document flow.

Static positioning is known to be the normal way that all element have or gets. It implies that one should "put the element into its original place in the document flow as there is nothing special that one needs to see here."

Hence,  the behavior of an element with static positioning is known to be the same and thus If a person do save and refresh, there will be no changes except when there is an updated background color.

i) It is difficult to put the mouse pointer's insertion point in the text

ii) A gray border appear around the time and date when you point to it

Explanation:

When the date and time is pointed to or hovered using the mouse pointer, we have, that the background of the text changes to a grey border around the text when the date and time is inserted as a special object using the insert date and time button on the insert menu in the word processing application

The mouse pointer behaves different when working with some applications, and it could be difficult to place the insertion point of the mouse pointer in the  text

Therefore, the correct options are;

It is difficult to put the mouse pointer's insertion point in the text and

It is a power-saving mode for a computer.

It is a power-saving mode designed for laptops.

Answer:

(a): power(2&-2)

The code is as follows:

power = 2**-2

print(power)

(b): Largest and smallest in a list

The code is as follows:

num = [33,6,11,100,456,109,-4,366]

smallest= min(num)

largest= max(num)

print(smallest)

print(largest)

(c): Loop in Python

(i) Loop are instructions that are repeated until a certain condition is met;

(ii) For loop, in python are used to iterate over a sequence or through a certain range;

The syntax is:

for loop_element in range(iterating_range):

The following is an illustration of for loop that iterates 5 times

for i in range(5):

Explanation:

(a): power(2&-2)

The ** is used to calculate power.

So, 2**-2 represents 2 raise to power -2

power = 2**-2

This prints the calculated power

print(power)

(b): Largest and smallest in a list

This initializes the list

num = [33,6,11,100,456,109,-4,366]

This calculates the smallest using min() function

smallest= min(num)

This calculates the largest using max() function

largest= max(num)

This prints the smallest and the largest

print(smallest)

print(largest)

(c): See answer section

Answer:

The correct option is a. correcting others’ spelling and grammar.

Explanation:

Note: This question is not complete as the options are not included. The complete question with the options is therefore provided before answering the question as follows:

Dana frequently joins people in online discussion boards and forums. Which of her habits should she change to maintain proper netiquette?

a. correcting others’ spelling and grammar

b. using a conversational tone

c . breaking large comments into readable paragraphs

d. typing whole sentences with capital letters

The explanation of the answer is now given as follows:

Grammar lessons should not be given in a casual conversation unless the person is a language teacher or has been specifically asked to assist. This indicates that correcting others' spelling and grammar in a normal conversation is often considered impolite. It's simply not polite and a sign of lack of etiquette to criticize the actions of other people when you have not been specifically appointed or when you are not in a position to do so.

Therefore, the correct option is a. correcting others’ spelling and grammar.

Answer:

The answer is "0.306".

Explanation:

The Primary to Secondary Memory Instruction miss cycle

[tex]= I \times 0.01 \times 10 = 0.1 I[/tex]

Data miss cycles[tex]= I \times 0.05 \times 10 \times 0.40 = 0.2 I[/tex]  

The Secondary to main Memory Instruction miss cycle[tex]= I \times 0.01 \times 200 \times 0.0002 = 0.004 I[/tex]

Data miss cycles[tex]= I \times 0.05 \times 200 \times 0.0002 = 0.002 I[/tex]

Total memory stall cycle [tex]= ( 0.1 + 0.2 + 0.004 + 0.002 ) I =0.306 I[/tex]

Answer:

Effort = 70 N

Explanation:

A machine is a device that can be used to overcome a load by the application of a minimal effort. For a practical machine, mechanical advantage (MA) is the ratio of the load (L) overcome to the effort (E) applied.

i.e MA = [tex]\frac{Load}{Effort}[/tex]

In the given question, MA = 5 and the load = 350 N. So that;

5 = [tex]\frac{350}{E}[/tex]

E = [tex]\frac{350}{5}[/tex]

  = 70

The effort applied to the machine is 70 N.

Explanation:

HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.

Generally, all HTML documents are divided into two (2) main parts; body and head. The head contains information such as version of HTML, title of a page, metadata, link to custom favicons and CSS etc. The body of a HTML document contains the contents or informations that a web page displays.

In this scenario, Roger wants to give semantic meaning (an element conveying informations about the type of content contained within an opening and closing tag) to a contact information placed at the bottom of a webpage. Thus, in order to do this, he should use a footer element as a parent of the contact information and as such all instance variables that have been used or declared in the footer class (superclass) would be present in its contact information (subclass object).
