Simple question.?
Ok, you have an electroscope and a rod that is positively charged, and you also have a marble.

Is the marble positively, negatively or neutral charged? Why?





Thank you

I'm not looking for controlled substances. I want to find something that isn't very dangerous. I'm looking for something that I can premix with my fuel so that I can get more efficient combustion.

I heard this is a 5-6 years program. Is that true? What is engineering? It would be weird that someone whos about 20 and wants to go for this degree would probably end up graduating at the age of 26. That can't be good. Can it?

My mother told me *not* to put anything metal in the microwave oven -- fork, spoon or even a gold plated tea cup. Now Campbell's soup "Ready to Go" product has a zip lid which is removed but leaves a metal lip -- why does this not spark? [I tried the fork and Mom was right!] Here is the soup product ...

Buildings are usually insulated with materials such as fiberglass, which contain pockets of trapped air. The insulation in buildings helps keep warm air from flowing out of buildings in winter, and likewise prevents the warm air from flowing into buildings in summer. What is the best explanation for the effectiveness of insulators such as fiberglass?


Gases, such as air, are better insulators than solids or liquids.
Heat transfer is accelerated with materials such as fiberglass.
Fiberglass is resistant to cold.
Fiberglass is resistant to heat.

heat pump to house subjected to ice storm exterior is covered with ice (approx. 80%) I don't want it to get worse due to similar problem a couple of years ago which resulted in replacement of heat pump. Do I need to defrost? Or do I ignore and hope for the best. I have heard to either set to emergency heat mode or to set to cool. Any answers out there?
