suppose you have a light bulb that emits 10 watts of visible light. how far away would you have to put the light bulb for it to have the same apparent brightness as alpha centauri a in our sky? (hint: use 10 watts as l in the inverse square law for light, and use the apparent brightness given above for alpha centauri a. then solve for the distance.)
