I need to explain a physics project tomorrow and I've tried to understand it but I'm just not sure.I'm using aluminum foil tied on a string, and a ballon which will be rubbed on the hair so it can become active and attract the foil.All I know is opposites attract, the ballon and the foil are at the same level but when the ballon is rubbed it become positive while the foil stayes neutral?I'm confused.
rearrange your furniture for 17 minutes
invest in a standing desk like the ergotron workfit s 379 ergotron com or get crafty and raise your monitor and keyboard with books
yeah fiber is an awesome thing, i normally go twice a day to, and have stayed the same weight for the last 6 months, even though i'd like to lose a little
Electrons are always negativeProtons are always positiveWhen you rub the balloon on your hair, electrons go from your hair to the balloon, and the balloon becomes negatively chargedThe foil is neutral because it has an equal amount of electrons and protonsWhen you place the balloon next to it, the foil's protons are attracted to the electrons in the balloonAll the protons will move to one side of the foil (the side closest to the balloon) and all the electrons will move to the other side of the foil (the side farthest from the balloon)The foil moves because its protons are trying to get to the balloon.
