Why does your hair stand up while gaining a charge from the Van de Graaff machine?
Because its exciting
The positive charge from the machine is transferred to your body, making each hair positively charged and attracted to one another
The positive charge from the machine is transferred to your body, making each hair positively charged and repelled from one another
The machine is taking the positive charge from your body, making each hair negatively charged and repelled from one another
Why does the Van de Graaff create a spark when the opposingly charged wand is placed near it?
Because its magic
Air doesn't emit light when the ions recombine with electrons from the wand, you are seeing things.
As the negative charge from the wand and the positive charge from the generator move through the air, it exites air molecules, causing them to give off light.
because it's broken
Explain why this is happening
The plates are being blown away by the wind created by the Van de Graaff
The plates are rubber so do not conduct electricity and are pushed away
The pans all gain the opposite electrical charge from the Van de Graaff so are attracted and push away from the Van de Graaff
The pans all gain the same electrical charge from the Van de Graaff so are repelled and push away from the Van de Graaff

The image is an example of which type of non-contact force?
Magnetic
Electrostatic
