Need . i'm stuck! 1: telepresence provides the opportunity for people to work from home and attend virtually. true false 2: when searching for your word processing file to finish writing your report, you should look for a file with which extension? a doc b exe c jpg d xls 3: moore's law states that the number of transistors on integrated circuits doubles approximately every two years. true false 4: if your computer is frozen, what is something you would do to troubleshoot the problem? a check if the monitor is plugged in b make sure your house has electricity c restart your computer d turn on the printer@chazmo

I believe 1. is true, Telepresence is essentially things like video-chat that allows people to participate in meetings even if they are not physically present.

2. In my opinion the answer is A. doc, xls is a spreadsheet file, jpeg is an image file and exe files are typically executable command files for operating systems.

3. true To my knowledge this statement accurately represents Moore's Law

4. If your computer monitor is frozen than it is pointless to check if the monitor is plugged in or if the house has power. If either of these were true the monitor would be blank. It would be even more pointless to turn on the printer as it should have no effect on the monitor.
The answer is c restart the computer, usually this will remove the problem and unfreeze the monitor.
