There also the fact that water molecules are polar, and air molecules are mostly non-polar. You might be able to have a selective barrier based on that.

The problem with metal in microwaves comes from the fact that electricity flowing through the metal will arc between two points that are nearby in space, but not in distance along the metal. For example, the ends of the tines of a fork are a few millimeters away from each other in space, but several centimeters along the metal. A fork will definitely spark in a microwave. A knife on the other hand is mostly one flat continuous piece, and would probably be fine in a microwave. Its the same thing with aluminum foil unless its perfectly flat, it will arc between two close pieces. A metal rack designed to be microwavable will take these facts into consideration. You should stick with the racks that came with your microwave though, a metal rack for oven use might still spark. Xenoborg fucked around with this message at 22:07 on Mar 5, 2013 |

Also unless I'm forgetting something, the the units don't matter for that problem. You take (m1*t1+m2*t2)/(m1+m2). This gives you an answer in whatever units t1 and t2 had in the first place.

brylcreem posted:Imagine this said in an English accent by a police officer: It pretty much means "Tell us what happened now, don't try and invent a sorry later, or we will ask why you didn't have that story in the first place." For instance: you are found at a murder scene covered in blood, and refuse to talk to the police. Later in court you claim you saw someone else kill the man, they are going to question why you didn't say anything at first. It doesn't mean they totally discount your later story, just that they consider it less reliable.

When playing some old games, the colors on my desktop wash out and I get a message saying windows has gone into basic color mode. I'm ok with it turning off the advanced features like transparency, but what I hate is the color scheme it reverts to includes extremely light blue windows with white text that I cannot read with it hurting my eyes. I can't find anyway to change these settings, but I'm sure there must be. edit: I was going to take a picture, but apparently print screen is turned off by this as well.

I finally got a blue ray player for my computer, and I'm trying to watch a movie with it... only I guess it needs something else. On my computer the disk shows up and you can look around as all the hundreds of files on it, but when I say with with WMP or VLC like I would a DVD it gives an error message that it can't open or can't recognize that kind of file. Is there some other program I need to be able to watch blue rays on my computer? On further investigation it seems that computers are just flat out unable to play blue ray movies?

Crankit posted:Yes that is bad, but not normally dangerous, this will lead to elevated CO2 levels for you both and if carried on for a while you'll feel how you do when you hold your breath and need to breathe, however this instinct will save you and you won't die. If you were to do this with a baby or pet they would almost certainly die, 18 children died from this form of asphyxia last year in the US. Is this a joke answer? Exhaled breath is almost the same as inhaled breath in terms of gas composition. It looks like a single "breath" of air could be used 4 or more times before being too saturated with C02. Since gases mix freely though, breathing in someone's exhale would never be an issue other than cases where your both in a small airtight box, and even though it doesn't seem like it would kill you any faster.

Most generally, I would say the that a place is a restaurant if you sit down an order from a server who delivers your food, and fast food or a cafeteria otherwise.

How fast does bad bacteria or whatever build up in milk residue in a used glass? I drink milk with most meals, and usually just leave my empty glass on the table since I'll be back to in a few hours to use it again. My roommate insists that even after just 4 hours, bad stuff will form in the residue, and that I should use a new glass every meal. It seems like a waste to me use 2-3 glasses a day like that, and she claims that just rinsing it isn't enough. Am I being lazy or is she being overzealous about germs?

You could try an ankle brace depending on how long of a time frame your looking at, just say you sprained it really bad. edit: If they mind in the first place.

Kurzon posted:I read an article in a science journal that explained why zebras never evolved gatling guns, even though such an adaptation would be a great defense against lions. It talked about exapation, saying that a complex adaptation must arise from a series of simpler, useful adaptations. I think they forgot to mention that miniguns use materials that are not really available to living organisms. Wires as we know them are pretty unlikely to ever be developed by a living organism, mostly because they are an inefficient use of a rare-ish material. But wires as a concept, something that transmits electrical signals, have evolved. Every animal larger than a few cells has them, we just call them nerves. Additionally, there are animals like eels that can use electricity to attack other creatures. There are even some animals like Pistol Shrimp that have evolved a close analog to a gun to hunt with.

muike posted:Why is waste energy expelled as heat instead of another kind of radiation? All temperature is is how fast particles are moving, so kinetic energy is heat, and every type of electromagnetic radiation can heat something up. Microwaves produce microwave scale radiation to transfer heat. Heat lamps and light bulbs produce mostly visible and infrared radiation that transfer heat. Tanning beds make UV radiation. Even the extreme ends like radio waves and X-rays transfer heat, but just not in conditions that would be safe for you to notice it. All objects that are hotter than their surroundings will emit heat in the form of radiation. The type of radiation is dependent on the temperature of the object. In the 0-300 degree C range the radiation will be infrared, which we can't see (but things like infrared goggles can). In the 300+ degree C range things will start to emit some of their energy as visible light and glow red like molten metal. Hot enough in the 5000+ degree range and something is glowing yellow like our sun. Any much hotter and the color gets washed out since we can't see UV light, so things just glow white. PS: Its annoying that both electromagnetic waves and nuclear decay products are both called radiation, when they are two different things. There is some common history with gamma radiation, but it's confusing to a lot of people who just think radiation = bad.

So its raining pretty hard in St. Louis, and the Nation Weather Service just issued a flood warning for my area. Uncommon, but not unusual, and won't effect me. What was unusual is the way I got alerted. My phone, a pretty much factory settings iphone 4, just sent off a siren with the flood warning as a message. It wasn't a text or call, it just showed up over the main page. I've never seen or heard of anything like this, is this something new and how did they do it?

Assuming 100% concentration on both you have: 100% * 950ml * 1.22g/ml = 1159g / 46.03g/mol = 25.18 mol of HCOOH 100% * 950ml * 1.84g/ml = 1748g / 98.08g/mol = 17.82 mol of H2SO4 Their reaction is, 1 + 1 -> 1 + 1 H2SO4(l) + HCOOH(l) -> CO(g) + H2SO4:H2O(l) So you would end up with: 7.35 mol HCOOH 0 mol H2SO4 17.82 mol CO 17.82 mol H2SO4:H2O The H2SO4:H2O and remaining HCOOH remain a liquid, the CO becomes a gas. Under STP 17.82 mol of CO becomes: V=17.82mol * .08206 * 298K V=435 liters A gallon each (4x as much) would make 4x as much gas. Either way, its a ton of CO which can quickly suffocate someone in a close space, and the reason this reaction is a dangerous one. It's also likely that you do not have pure concentrations of either acid, but starting from the beginning you can carry that change forward.

change my name posted:It was a story on evolutionary circuits featured on damninteresting.com. I'm pretty sure it was true. http://www.damninteresting.com/on-the-origin-of-circuits/#continue Sounds pretty awesome. It should be noted that the evolved circuit did not preform better than a traditional one designed to do the task. It was the facts that it did it without being designed by a human and that the design took advantage of magnetic effects that are usually ignored or mitigated in traditional design. That the evolved design would not work on other FPGAs indicates that the it was using features on smaller scale than the FPGA's design tolerance which may be interesting for miniaturization.

I've never understood why gas prices such a big deal in the US, both political and to the average person. I pay more for food than I do gas, I pay more for utilities, I pay more for my phone/internet, and I pay many more times for rent. You never heard people talking about these prices, but if gas goes up 10 cents, you had better bet it will be on the news and people will complain about it even if its just costing them a few dollars a week. Especially since gas in every other country is several times more expansive.

XBurritoXLogicX posted:How do carcinogens and radation that a person isn't constantly exposed to cause cancer later? For example a bunch of people that survive a large dose of radation all dying early or in the same time frame of various cancers. A lot of times it has to do with inhaling/ingesting atoms that are still radioactive themselves. For example a radioactive isotope of iodine is produced in nuclear meltdowns/bombs. Our bodies need iodine and it isn't super common (well its added to salt these days to take care of that), so we store it up. The body can't tell the difference between regular iodine and the radioactive kind, so it's happy to store radioactive iodine in your lymph nodes, where the continual release of radiation can cause damage over a longer timescale. This is reason why iodine pills were given out, they were to "fill you up" with regular iodine so your body wouldn't try and store the radioactive stuff. The second possible answer is that while radiation does immediately damage a cell, it can take a while for a single bad cell to become a problem. The classic case here is radiation induced cancer. One bit of radiation damages one cell in a way that makes it cancerous. It will still take time for that single cell to grow into a tumor large enough to cause problems.
