I haven’t been able to talk to her cause of certain reasons, but she talked to my sister the other day and told her that she missed me and wanted me back. I don’t want to get hurt again, but I miss her and I love her.

I love science a lot, but I haven't been able to figure this one out. Why on earth would hydrogen, (a combustable element) and oxygen (An element fire needs) chemically create a compound that does the exact opposite. I know it's a new chemical, and isn't neither hydrogen or oxygen anymore, but still... always bothered me.

I just bought it today and was wondering how long do I take it before going to bed? Also they come in 3 mg per pill. I'm 13 with Insomnia. No doctor will help me for some reason, I think my family doctor said that he doesn't want to make me get dependent on a drug (not that I want to be put on drugs).
Thanks for your answers!

Circle, 12 feet diameter.
Pins sticking out of the circle, 0.3 inches.
Imagine the the chord line as secure base for the pins (Therefore pins are longer towards the middle but still only protrude 0.3").
The pins can vary to a maximum of 3.5 degrees off tangent.
What is the widest chord possible given the above?
If all the pins were tangental, the pins could not be withdrawn inwards from the circle. This is the key part, the pins which are attached to the chord must be able to move inwards, hence using the 3.5 degree allowance to keep the pins at 90 degrees to chord.
