Semen needs to be fairly deep into the vagina to cause pregnancy. So unless you stuff your underwear far up there, you're probably not in too much danger. Still, it's not a good idea - it gets sticky and cold after a while.
If semen falls on your undergarment and you wear it for another half an hour, it is recommended to wash the undergarment as soon as possible. Semen can contain bacteria and may lead to unpleasant odors or potential infections if left unwashed. It's better to err on the side of caution and clean the garment thoroughly.
The speed of a falling object keeps changing as it falls. If an object falls 250 feet to the ground and there is no air, then it takes about 4 seconds to fall, and it hits the ground at about 86.5 miles per hour (127 fps). If the object falls through air, then the speed it picks up depends on its weight and shape ... a sailplane falls slower through air than a rock does, but take away the air, and a rock and a feather fall together.

There are only one group of 3600 seconds in one hour. One hour is equal to 3600 seconds.
An hour is 3600 seconds, and a nanosecond is a billionth of a second, so an hour is 3,600,000,000,000 (three point six trillion) nanoseconds.
It is per hour: 24 kW = about 81,891.4 BTU per hour.

Normally semen coagulates after it is extracted. It doesn't start to liquefy for about 20 minutes to an hour after its release. The best way to improve liquefaction time on semen would be to talk to a doctor.
About a 13 hour drive.
Semen is initially thick and viscous due to proteins which form a gel-like substance. When this breaks down, the semen becomes thin and watery. In humans, this usually happens in under 20 minutes (and isn't directly connected to being "in the female"), but anything less than an hour or so is considered within the normal range. Semen that doesn't liquefy within an hour is a potential cause of infertility.
About 3.24 billion (3.24*1010) gallons of water per day flows over Niagara Falls.
I believe about 1/2 an hour is what I have read.
About one hour.
