How many AA batteries will you need to make a 100 watt light bulb last for two weeks?

Depends entirely on the batteries - all types and brands will have a rating, usually in mWh - you need to work it out from that. You also need to allow for the rated voltage of the lamp. Educated guess - very many thousands.

What watt of a bulb can a 9 volt use?
9 volt alkaline batteries are not really meant for heavy discharge loads, and are not normally used to power lamps. The practical limit for any reasonable battery life would be about 0.5 watts. At this power level, you could expect athe battery to last only 2 to 3 hours for incandescent, and maybe up to 5 hours for an LED.
How can you wire and control 3 lights from 1 switch?
This is simple. First the wire coming from the power supply go to the switch. Then it goes to the first , the second and the third light. Since the switch comes first all three light will be controlled by that one switch.

How do light a light bulb with a car battery?
A car battery normally supplies 12.5 volts at full charge. If the light bulb you are trying to light is a 12 volt bulb then make a connection with the +(positive) battery terminal to the small lead button at end of the bulb, and the - (negative) terminal to the metal side of the bulb. If the battery is charged, the light should work. If the bulb is a higher voltage type you must connect more batteries in series until the proper voltage is reached. WARNING...With more batteries connected in series, the voltage could become dangerous. Do not use more than two batteries in series unless you have an experienced electrician to apply safety techniques. If your battery is 12 volts, an auto lamp up to 24 volts will light up. the 24 volt bulb will be half as bright. Over the years, I have replaced dashboard lamps with 14 volt bulbs because they will last longer because they are rated for a higher voltage but fed with a lower voltage.
