Q:First and foremost,what happens when resin and hardener[unmixed] are left at room temeprature?Will they hardener?I'm quite sure both will not harden unless they're mixed but i need some comfirmation.Secondly,When resin is heated or hardener is heated,their viscoisty are reduced.What happens when they re heated at high temperaure for an extended period?I assume they degrade?Sorry,i don't have access to DSC ATM but need to type a report asap
It probably brings an electrical overload into your kitchen. That can cause smoke, even if you can't see it.
Q:Is this part of the most transparent administration in US History that Obama lied about?
you still managed to post a Question on here.
Q:I'm planning on getting a nose piercing done this week and wearing a stud. Later down the road.. be it years or months.. would the hole close completely up like there was nothing there if I changed my mind and took it out for a future career/family/etc? Or will there always be a hole or obvious bump there?
I don't know the correct way to but when i was a kid my mom used a screwdriver or a knife and pry it out it always worked to. But be careful not to mess up your VCR in the process.

If you don't know what tools you need, then you really don't need to be tuning on your cruiser. I know you may need to save money by doing it yourself, but messing with something you don't know about, usually ends up costing you twice as much in the long run. Better to leave this to a mechanic, as he would have all the tools needed. Besides tools are expensive, and someone trying to straighten out what you messed up will cost you dearly! You might be able to tune on it with a basic tool set like the $120 mechanics set that sears has on special. It's a good set, and had most of the basic stuff you might need for doing plugs, wires, cap rotor. Thats really all you need to do to it. Do yourself a favor and put the same plugs in it that comes in it, and stay away from those high dollar plugs that don't do any better or last as long as what comes in it. Don't try to adjust anything like the timing, the injector system, or idle speed, as all of this is don't by the computer now. Do not try to take the sprk plugs out of a warm engine or you can damage the head. Work on a cold engine with stuff like that. Good luck!!
Q:How long does the smoke alarm battery last?
Users can also press the self button on the smoke detector periodically, listen to the size of the alarm sound, and determine whether the power is adequate
Q:will pounding on the floor set off a smoke detector on the floor below?
Every half-life, an isotope will lose half of its activity due to radioactive decay. Therefore, you can roughly calculate as: 1 half-life 433 years 50% of the original activity 2 half-lives 866 years 25% 3 half-lives 1299 years 12.5% 4 half-lives 1732 years 6.25% 5 half-lives 2165 years 3.125% 6 half-lives 2598 years 1.5625% 7 half-lives 3031 years 0.78125% Therefore, the source will decay below 1% of its original value in roughly 3000 years. You can calculate the decay exactly as: ln(0.01)/-e^(432.7*365.2422) 1,050,220 days. Therefore, a 1uCi source on December 3rd, 2010 will have 0.01uCi on April 29th, 4886 Ionization smoke detectors are still in use today because they are excellent detectors of fast flaming fires, whereas photoelectric smoke detectors are excellent detectors of slow smoldering fires. The dose one will receive from an ionization smoke detector in one year is less than the average american will receive from all sources (sun, food, granite counter-tops, flying, etc) in one day.
Q:I know there are tons of kit for sale out there, but I really do not know which brand / product is the best one to have? I see a lot of Youtube video on how to survive economic crash and get prepared for it, etc. Everyone has a great knowledge and skills. But I do not really know what KIT to prepare for myself.. any advice ?
Some smoke detectors do that when you first put the batteries in or if you hit the 'silence/test' button. It continues for about five minutes then stops. Check the manual that came with it.
Q:Seniors, do our animal friends really care about the niceties?
Because there is no battery backup, it is telling you that it is not protecting you until power is restored again

Ball Pythons are easy snakes to keep, as long as you get their basic husbandry correct, and make sure you get one that is a well established, feeding baby (or older snake). A very basic list of necessities to keep a Ball Python truly healthy would include: Enclosure(obviously): Something secure and that will hold heat and humidity. Under tank heater: Some pet shops will tell you that they can be kept warm with overhead lighting, but Ball Pythons require a fairly high humidity level to thrive, and overhead lighting dries this needed humidity out terribly. Snakes also need belly heat to digest their food properly, wich overhead lights do not provide well. Thermostat for heater: this keeps the temps at the appropriate levels, not too hot, not too cool TWO secure hide boxes: one for the warm side, one for the cool side Water dish Substrate (bedding) 2 thermometers: One for the cool side, one for the warm side. Do NOT get those that just stick onto the glass, they are very inaccurate, and don't even measure the temps where your snake is actually laying. Ball Pythons require a hot spot temp of 90-92 degrees to digest their food properly, and be comfortable. The opposite end of the enclosure should be kept in the low 80 degree range. They need to feel safe and secure to eat, therefore the 2 hides are needed so they can thermoregulate properly. The idea of feeding in a different enclosure is a myth. If you are going into your snake's enclosure daily as you should be to handle, check water, spot clean, check temps, etc.there is absolutely no reason that feeding once a week will condition them to think food when you open the enclosure or reach in there. If that were the only time you opened the enclosure, it might pose a problem, but when the snake is properly cared for, they do just fine fed in the same enclosure. Ball Pythons often will not eat if moved out of their comfort zone..aka their home.
