Answer:

A. Document camera

Explanation:

Document cameras, which are also known as visual presenters or visualisers, digital overheads, or docucams. They are real-time image capture devices for displaying an object to a large audience. Just like an opaque projector, a document camera is able to magnify and project the images of actual, three-dimensional objects, as well as transparencies. They are, simply put, high resolution web cams, that is mounted on arms so as to facilitate their placement over a page.

This makes it easier and convenient for a teacher, lecturer or presenter to write on a sheet of paper or to display a two or three-dimensional object while the audience watches.

In Theory, the document camera can be used to display all objects.

Gwen only needs to place her photo under a document camera and deliver her speech while the image will be displayed for the class.

What would be the total width of the div in the code below?
Artyom0805 [142]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The correct answer to this question is d- 346px.

The complete code of this example is given below:

<div>

style="margin:20px; border:solid 3px #888888;">

</div>

while the image width is 300px.

It is noted that the image width is 300px and the margin is 20 px.

Margin:20px means that image margin from four side is 20 px each.

So the width of dive from both side increase to 40 px and the image has 300 px, then total width becomes 340px. Now the border also has 3px of four sides of the image, then the width of the border becomes 6px.

so the total width of the div tag is 346 px.

In short, we can calculate the width of tag as below:

total width of div= width of image+ width of margin+ width of border

total width of dive= 300px+40px+6px

total width of div=346px.

Explain the differences between copyright, fair use, and trademark?
ValentinkaMS [17]

A trademark is an easily recognizable symbol, phrase, or word that denotes a specific product. It legally differentiates a product or service from all others of its kind and recognizes the source company's ownership of the brand.

"Copyright" literally means the right to copy but has come to mean that body of exclusive rights granted by law to copyright owners for protection of their work. Copyright protection does not extend to any idea, procedure, process, system, title, principle, or discovery.

Fair use is a doctrine in United States law that permits limited use of copyrighted material without having to first acquire permission from the copyright holder.
