I have a plastic wheel glued to a metal axel, so the wheel will not turn. I tried soaking it in acetone nail polish remover, but it has been about an hour, and it still wont move. I would buy super glue remover, but I read that it is just acetone. Any suggestions?

Every morning with breakfast I take 2 pills (prescriptions) and 1 capsule (supplement) -- all at once. Instead of carrying around 3 bulky bottles in my purse with me all the time, can I just put all 3 together in one bottle instead, and fill the bottle as I need to? Is there any danger in doing this? The scrips are Celexa and Vytorin and the supplement is CQ10.

Here are the problems I need help solving "x" for -

tanx=-4sinx

csc²x=7tan(90° - x) - 11

5sin(90° - x) = sinx

6cos²x=7-5sin x

If you can help with any, I would be so grateful!

Cheers!

If an asteroid was going to hit the Earth, could we use nuclear weapons, or would the radiation come back and hit us?

God could kill all the evil people on earth then bring those in the space station back to replenish the Earth and start all over again. Instead of a rainbow he would give them a complete circle, a rain circle. Yea! Clap clap your hands. BB

i know that when the light intensity of a light source falling on an LDR is high, the resistance in the LDR falls and when the light intensity is low, the resistance of the LDR is high.
and i know that when resistance is high, current flowing through the LDR is low and vice versa.
however, whats the relationship between the voltage and the current in an LDR? are they directly or inversely proportional?
if the current in an LDR rises, will the potential difference also rise or fall?
this is quite important as i need it for this sensor i'm making at school.
if u've got ur information from a website, could you also mention the website here or create a link?
thanks

Hint: Rate x Time = Distance

Ok....i got awkward answers..but im hoping someone else will figure this out.

Hi,
I do Physics (GSE level only) and am interested in knowing what Einsteins Theory of Relativity is in simple terms.

I just want to know what he has said, how it helps us, and what does this mean about time stopping ... .

Thanks, remember in Physics terms, but relatively simple as I am not doing higher physics yet.

Thumbs up... for all you answers, and thanks!

My teacher allows us and promotes the use of calculators and programs etc.

I already know how to do most math problems, but I often write them down wrong or do stupid mistakes, and a calculator that can do alot of things would be a great help.

Looking for something that can solve for x or y all by itself etc.

Please don't get all technical and say you need more information, just give me some links to what you might think would be the most help to me! Thanks!
