Android Acer Iconia A500 connect to VGA projector for A/V streaming?

[Tabletlady]

Is it possible, and if so how ... what kind of adaptor &/or cable output & input.. where to purchase (Oakville/Mississauga) ONtario
to be able to connect an Acer (android) Iconia A500 tablet to a VGA projector to show video and audio streaming e.g. Youtube, or educational streaming....
Is audio and visual possible with a cable adaptor..not just power point/visual capablity? If so, how?

Thanks
