Physics questions which I need stock knowledge answers for :)?

Please answer this based on your stock knowledge or own theories. :) No researched answers please? 1.) What is the function of a cellphone charger? Why is it called a charger? Does charge have anything to do with it and its voltage?2.) Why do clothes often cling together after being tumbled in a clothes dryer?3.) Why are lightning rods a prerequisite in buildings?4.) What should you do when you are caught outside in a thunderstorm?Thank you! Need your immediate responses please. :)

Answer:

Depends on the type. A heavy CO2 would not but a lighter dry chem might. Two other types which would have a real good chance of floating are the older style (Soda-Acid) water/foam extinguishers. These were un pressurized units that were activated by inverting them. They were filled with baking soda and had a small container of acid in them which would empty when inverted. I suspect that once this older style was discharged that it would float quite readily. How ever any fully charged extinguisher (water, foam, dry chem) will probably sink like a stone when fully charged due to the extra weight of the media inside.
