180 degrees

• Question:-What would happen if the outside temperature got up to 180 degrees?
  What would happen if the summer temps were to go reach 180 degrees F? When will the buildings eventually start to fall down or crack? I live on the 3rd floor of an apartment building complex, and 3rd is the highest floor. Would the 180 degree temp outside have an effect on me or the building itself?
  
  Answer:-At that temperature, you would likely see some minor damage to your home. However, I would be more concern about how I can survive at least until the next cooling trend. The A/C would likely be of little help and there would likely be no power too. That heat can easily kill a person if you stayed in that apartment with no A/C,
• Question:-What is the name for the longitudal line at 180 degrees?
  I know that the Prime Meridian is 0 degrees on the longitude scale. But what is 180 degrees--the point exactly opposite the Prime Meridian on Earth?
  
  Answer:---The International Date Line (IDL)----------------The International Date Line (IDL) is an imaginary line on the surface of the Earth opposite the Prime Meridian where the date changes as one travels east or west across it. Roughly along 180° longitude, with diversions to pass around some territories and island groups, it mostly corresponds to the time zone boundary separating -12 and +12 hours Coordinated Universal Time (UTC) (Greenwich Mean Time – GMT). Crossing the IDL travelling east results in a day or approximately 24 hours being subtracted, and crossing west results in a day being added. The exact number of hours depends on the time zones. http://en.wikipedia.org/wiki/International_Date_Line -------------------- The International Date Line around 180° http://en.wikipedia.org/wiki/File:International_Date_Line.png
• Question:-On a Magnetic motor we need the polarity to reverse at 180 degrees to keep the motor in a constant?
  Is it possible to reverse the polarity at 180 Degrees on a Magnetic motor so the magnetic fields continue as overlaping increasing fields like it did from top to 180 Degrees. Without reverse polarity at 180 Degrees we have a break point.
  
  Answer:-A motor's torque is maximum when the rotor is about 90 degrees out of phase magnetically with the stator. Any more than that and the rotor again approaches equilibrium, albeit an unstable one. In most motors, it isn't so much the alternation of the magnetic polarities that provides the driving force so much as the the poles' rotation about the stator that drives the rotor. This rotation is inherent in a three-phase motor or a single-phase motor with a phase splitter. Otherwise, the motor requires a mechanical asymmetry between the stator and rotor, most often the result of the existing motion of the rotor or somewhat dodgy commutation with the armature. Such motors often have poor starting torque before the asymmetry is well-established or are less reliable than polyphase motors.
• Question:-How do I flip a powerpoint slide 180 degrees?
  I'm doing a presentation on Angels and Demons and would like to have the ambigrams flip 180 degrees in front of the audience without having to open up the tool bar in front of them and causing a lull in the presentation. I would like it to be a graphic of some sort so it rotates on its own. Is is possible to do this and how? I'm using Powerpoint 2008 for mac.
  
  Answer:-Duplicate the slide - (View --> Slide View --> click slide, Edit --> Duplicate) click the graphic on the new slide - select 'Draw' --> 'Rotate or Flip' --> 'Flip Horizontal' (if that choice is grayed out, ungroup and then regroup the graphic)
  
  
  give the slide a dissolve transition. don't use a jump cut, don't use a fade through black, don't use an up-left. use dissolve.
  
  
  done.
• Question:-How long should I bake Fish with Olive Oil on it at 180 degrees celcius?
  Hi,
  
  I've read some places that the smoking point for olive oil is 190 degrees celcius, so I decided to bake fish using olive oil at 180 degrees celcius, and it's been almost half an hour, and the fish seems not even close to being cooked.
  
  How long do I have to wait?
  
  Is there a better way?
  celsius*****
  
  Answer:-Nowhere near a half hour. Fish should flake with a fork and be at least 72 degrees celsius throughout for food safety.
• Question:-How many feet are in a circle that is 180 degrees in diameter?
  We are installing a wireless dog fence that's 180 degrees in diameter and are wondering what the footage is if we are to walk the whole circle.
  
  Answer:-Circumference of a circle is the diameter multiplied by pi. You can't measure the diameter in degrees, so I'll assume you mean feet, in which case the circumference of your dog pound will be 3.14159 x 180ft, 565.5ft.

• Question:-Is my homebrew going to be ok since I let it get up to 180 degrees during the boil?
  Today is bottling day for my Ruby red IPA. Two weeks ago when I boiled the wort I used a larger burner on my stove. I had not realized it was a larger burner and the beer boiled much quicker and got up to 180 degrees. For what it's worthI used a grain/extract.
  
  Answer:-I highly doubt you’ll have a problem. The “boil” temperature and length can affect grain/hop flavors infused into the wort along with the types of grains/hops used. For instance, if you’re making a whit that you only want to lightly spice, you’d add your bitter orange peal, coriander, ect... during your last 5-10 minutes of the boil. For stronger more pronounce flavor, you could introduce them earlier in the boil. Volume measurements and time length are the main differences between my homebrew IPA and someone else’s aside from ingredients.

generators

• Question:-Generators?
  I really don't understand. They say a big $1000 generator can only run for like 12 hours. Then you got to refill it, and each fill costs like $15??? But obviously you can run the electicity in your car for like months, am I right. And what is it in your car that lets you do that and how much does it cost? So can you buy one of those things seperately and use it for stuff like a small fridge, a tv, heater, so on... instead of a generator because its cheaper and runs longer???
  
  Answer:-it won,t put out the voltage to run your house
• Question:-generators?
  where can i find a sketch of a generator?
  (all its asking for is a generator, but im assuming a DC generator because the question that follows asks to explain what a DC generator does and how it works)
  
  
  I found the percent efficiency of a motor generator system. the efficiency was very low.
  where was the rest of the energy most likely lost to?
  (it was a basic motor system.
  battery ->
  switch ->
  motor 1 ->
  motor 2 (now acting as a generator because motor 1 is spinning it) ->
  light bulb)
  
  what impact do generating plants have on our environment?
  
  
  appreciate any help i can get.
  
  thanks.
  
  Answer:-there is an equivalent circuit diagram and other pictures on http://en.wikipedia.org/wiki/Electrical_generator
  you could also just try google image.
  
  energy from a genset can be lost to both heat and friction. Many electrical generators are powered by diesel engines. Generating plants that run off of petrol diesel emit sulfur dioxides, carbon, and other nasty junk into the atmosphere. Hydro generators (from dams) mess up the ecology of a river or lake and changes the geology of the surrounding area.
• Question:-Are generators allowed at national parks in the United States?
  Does anyone know if generators are allowed at campsites in national parks in the United States? I searched the National Park Service website, but couldn't find any overall policy statements regarding generators--just a couple of specific cases and exceptions. Thanks!
  
  Answer:-The rules are set by the individual park superintendents, and can vary from one campground to the next. Here in Death Valley, there are generator hours in most of the campgrounds. You need to go to the individual park website (they all can be found at nps.gov -- unless you are looking at USFS or BLM recreation areas) and find out the rules at the particular park and its campgrounds.
• Question:-How are different AC generators linked in a power grid?
  I've often wondered this. When you have two or more AC generators (say two different power plants) produce power, it seems like it would be impossible to be sure the two are in phase with each other. So how can the two be linked into a power grid? Is the same technique used when hooking up a home generator (from a wind turbine, for example) to supply the grid?
  
  Answer:-No. It's actually rather simple to keep them running synchronously on the power grid. All it takes is a simple phase comparator and a feedback control system to regulate the generator.

• Question:-How do you connect 2 basic generators together in series, to power a house?
  Generators are typical small ones that are usually bought at Lowes or a Home Depot. I want to hook them together to power my house.
  
  Answer:-I could give you a lot of techno speak to tell you why, but the bottom line is that it is totally impractical to wire them together. You can not syncronize them and that is manditory if they are connected together.
  
  In any case, it would be in parallel, not in series. Since it is impractical, that is a moot point too.
  
  A better idea is to split your house into two separate sections. One would be powered by each of the two generators. This is not that easy to do for most houses if you want 220v available. I will explain that in a minute.
  
  If you only need 110v, you can connect one generator to each side of your breaker box's main lug. It is obviously critical to make sure you are totally disconnected from the power company's grid when you do this. If you are connected, it will cause a world of hurt. You must be sure about this.
  
  Also be aware that the 110v output of the generator is probably not going to give you as much amperage as you expect. This is quite doable if you know enough about electricity to do it safely.
  
  That is the practical answer. A purely theoretical one would be to partition your breaker box into two sections. Each section would be 220v, just like the power from the power company. One generator would power one section, the other would power the other section.
  
  The reason that is not practical is that you cannot easily partition the breaker box. A breaker box has only one main bus for each side. For this to work with one box, it would have to have two main busses for each side. It is totally impractical for most uses. If it was really important to do this, a better idea would be to have two independent breaker boxes.
  
  Each would be powered from the power company as normal. If you needed to go "off grid," you would disconnect each box from the power company and connect the one generator to each box.
  
  This would allow you to use the maximum practical power from each generator and would be easy to cut over from power company to generator and back.
  
  The drawback is that you need a much more complicated breaker box setup. Most people would find this impractical.
  
  Again, it is critical to life and property that you know what you are doing and that you do it properly. This is not something to design yourself, especially if you think there was a way to connect them in series.
• Question:-How does one find the number of generators of a cyclic group?
  I have been given two cyclic groups, one of order 8 and one of order 60. No specifications beyond that. How do I find the number of generators of each?
  
  Answer:-The number of generators for a cyclic group of order n is φ(n).
  
  φ(n) denotes Euler's phi function, which counts the number of positive integers up to n which are relatively prime to n.
  
  Facts:
  (i) φ(ab) = φ(a) φ(b) if gcd(a, b) = 1
  (ii) φ(p^n) = p^n - p^(n-1) if p is prime.
  -----------------------
  1) There are φ(8) = 2^3 - 2^2 = 4 generators for a cyclic group of order 8.
  
  2) There are φ(60) = φ(2^2) φ(3) φ(5) = (2^2 - 2) * 2 * 4 = 16 generators for a cyclic group of order 60.
  
  I hope this helps!
• Question:-Are thermoelectric generators and coolers just the same in their structure?
  I am doing an experiment with thermoelectric generators.
  I need a lot of those things but the problem is that they're just too expensive. But when it comes to thermoelectric coolers, they seem to be cheaper.
  
  Can a thermoelectric cooler be used to generate electricity?
  
  Answer:-Essentially yes, though I'm not sure the components in a TE cooler are designed for it to work as a thermoelectric generator. I suppose it's worth a shot
  
  A TE cooler is, in theory, just a thermocouple, where the current is forced to run in the opposite direction; this causes one end to become warm and the other end to cool. The major difference is how the unit is designed to handle heat flow, which is why such a cooler may not work as a thermal pile.....
