100%, i promise!

Anonymous is 100% correct!

Your answers are except for the third one. Cell phones use microwaves (a type of radio waves ).

Thank's Student12!

No problem Angel :)

I don't agree with #2. Nanotechnology doesn't create new atoms.

To answer these questions, you need to understand the concepts being discussed. Here's how you can find the answers:
