romanna [79]

<h2>Hello!</h2>

The answer is:

Optical disks are circular disks used as storage for binary data usually made of polycarbonate. The data is stored in the disc using a laser machine and accessed using a laser diode illuminating the data path in an optical disc drive.

CD: Compact Discs are the most basic optical disk used today, with only a capacity that goes from 0.7 GB (700 MB) to 0.84 GB (840 MB).

DVD: Digital Versatile Discs increase the storage up to 6 times compared with a CD, the capacity of DVDs optical disks goes from 4.7 GB (4700 MB) to about 17 GB(17000 MB).

UDO: Ultra Density Optical have high capacity storage that goes from 30 GB (30000 MB) to about 60 GB (6000 MB).

dybincka [34]

Answer:

Honestly self driving cars are the future of humans and it can and will help us evolve. It could possibly be more dangerous if someone messed up the coding and it can be hacked by almost anyone with coding abilities, so it all depends on how safe you think you will be not driving yourself anywhere. Overall it could go both ways( good or bad.)

Hope this helped

I need answers and explanation

Answer:

B. Run-time Error

Explanation:

You can't divide by zero in math because it could be divided by itself an infinite number of time, which is not possible.

A. Syntax error is just the 'grammar' of the code. An example could be forgetting to add a semicolon at the end of your code in C. Another example is forgetting to close brackets or quotes

<em>printf("inclomplete string </em>WRONG, will give syntax error

B. Run-time error is an error that occurs while the program is running. This might happen because of many reasons, one of which is calculation errors such as dividing by 0.

C. I don't know what an Undetected Error is. Never hear of it.

D. Logic error is an error when a condition is not logically correct. This could be because you used the wrong type of operator.

if(a = b) WRONG, will give logic error

if(a == b) CORRECT

when you select cells in your worksheet and then click the copy button, what happens? select one: a. the formatting is removed f

Amiraneli [1.4K]

Hey there! Hello!

Not sure if you still need this answer, but I'd love to help out if you do.

In terms if Excel Spreadsheet, your answer will be D. A<span> moving dashed line border appears around the cells. What the copy button does is take the contents in your cell(s) and copies them so that you can paste them elsewhere. B and C would apply here if you were cutting the text, which clears whatever you have selected so that you can paste them elsewhere without having to go back and delete it.

I have attached an example of what happens to a cell when you either right click it and press copy, or press ctrl/command+c, which is the keyboard shortcut for copying text or contents.

Hope this helped you out! Feel free to ask me any additional questions if you have any. :-)</span>
