Turn teh bulb on, and the heat emitted from teh filament will evaporate it. Then, you will have only the water vapour left in the bulb

Depending on your location in relation to the equator, and of course your elevation, you could be correct. The right answer is that there is no right answer because not enough information is given. Did that make sense? If so, you need to go to sleep because I'm just rambling. |
You mean to say your ramblings will put me to sleep? :P j/k
The mosquito and skier makes a skeeter, no?

Ok, I feel dizzy.
but seriously, I thought that light bulbs had to be made with at least a slight vacuum and possible a stable nitrogen base. Having oxygen inside them causes combustion which degrades the filament.
I believe that this was the primary difficulty that Edison had to spend 10,000 tries to iron out. If there was oxygen (or water vapor one would assume) inside, it would cause the filament to burn and disintegrate.
That was way back when he was using cotton filaments though. Who knows what it is like now. |

Impossible. You can't cross a vector with a scalar.

Which is heavier?
A ton of gold, or a ton of feathers? |
It depends on what you mean by ton. If depends also on the force of gravity at each of their locations. |
Assuming all else is equal, a (troy) pound of gold would weigh more than a pound of feathers. You can extrapolate that to tons if you like.
 |
Nope,Nope, Nope! Book, Book, Book! 1 troy pound=12 troy ounces and one troy ounce=31.103 grams, thus one troy pound=373 grams while one pound avoirdupois=16 ounces that are each 28.35 grams for a total of 454 grams/pound vs. 373 grams/troy pound! Therefore the troy pound of gold will weigh less than the avoirdupois pound of feathers by 81 grams. Yip, Yip, Yip! Brrnnnggg!

You can still add the magnitudes

Or multiply them together...

"What do you get when you cross a mountain climber with a mosquito? "
Insect rappellent.
"If a clock is set to go off at 5:00 PM and a rock is thrown 25 yards, how much water is in a lightbulb?"
No soap, radio. |
