Chem help??? im stuck....? i know the answer, but not how to get it.?
Well, the answer *can't* be 2.9 * 10^-23cm, as that's a measure of length, not volume. But assuming you just missed out, or couldn't type the ^3 to signify that, then you have the radius of the sphere, the volume is 4pi/3 * r^3
Please do not answer unless you KNOW the answer. What domesticated dog/dogs can kill a wolf 1 on 1?
Most large dogs could put up a reasonable fight. The problem is that wolves usually come in packs and work together, so they can dispatch a dog pretty quickly as a team. Any sort of fighting dog would kill a wolf quite easily, these include Pitbulls, Akitas and Mastiffs among others. I might add that fighting dogs are completely different to working dogs, and could not be used effectively when hunting game in a pack. The phrasing of your question is quite strange - "hold off a wolf" - wolves are endangered species and it is illegal to hunt them in most places. Even when they are hunted, it is by one man with a gun, not with a pack of dogs. The only occasions that I know of where dogs are used for hunting is foxhunting, which is now illegal in the UK, the only place where it happened. Other dogs are used in conjunction with other types of hunting but these are retrievers and pointers, used in the hunting of birds, like pheasants and partridges. These dogs would never need to fight anything. Wolfhounds could very easily kill a wolf, they were bred for it, as the name tells you. Still don't believe it? here's a video of a wolfhound killing not one, but TWO wolves : http://uk.youtube.com/watch?v=3170gvlnPwU&feature=related EDIT: there was a guy before me who said that " their bites are more then twice as powerful as any domesticated dog, including the pitbull" - this is a load of rubbish, a Pitbull's bit is far, far stronger, they were bred for fighting, they may look small but this is so they can get under bigger dogs and bite their soft undersides. He also said that "dogs for the most part are not wolves", which is also not true, all modern dogs are decended from wolves, and are only different because of extensive breeding. A wolf is certainly a dog. There is also a lot of idiots saying that no dog could kill a wolf, this is absolutely not true - waimeranas were bred to kill bears and Rhodesian Ridgebacks were used for hunting lions, they would have no trouble with a single wolf.
Physics Question, please help, I know the answer but not how to get it.?
I needed to write it out for clarity: I messed up on the integral it should have been du/u not u/du, but it was a miss writing, the solution is still accurate.
Angular velocity problem? I know the answer, but not how to get there?
I have the answer, but no idea how to get there. I've been trying different ways to do it but the answer eludes me. A machinist turns the power on to a grinding wheel, at rest, at time t = 0 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 91 rad/s. The wheel is run at that angular velocity for 33 s and then power is shut off. The wheel decelerates uniformly at 2.9 rad/s2 until the wheel stops. In this situation, the average angular velocity in the time interval from t = 0 s to t = 25 s is... Answer: 55 rad/s What I tried: First I found first acceleration, which I found to be 9.1 m/s^2 I know the average will be change in angular position/change in time. I just can't seem to get the answer though.. How do you do this?
I think i know the answers, but im not sure.. if i get these right i'll have a 100, pleasee help:)?

Do you ask questions not precisely to know the answer, but only to get to know the person you are asking the question?
Wait, doesn't everybody do this? I'm pretty sure most people learn more about you by observing you, or hearing a one-off comment while in your company, than they ever do in a direct line of questioning. If you're not sure about that, think about a family member you grew up with. I can tell you all about my brothers' lifelong favorite hobbies, tastes in music, what they dislike, what they could talk about forever, the girls they've been interested in, favorite styles, foods, etc... It's not because I sat down and asked them all these things, it's from spending time with them and knowing who they are, picking up on what they make conversation about. Still, I believe asking people questions is a great way to get to know them. Afterall, people genuinely enjoy the attention of being asked. Ever seen somebody get mad because they didn't get informed of something they probably wouldn't have even cared about in the first place? What's their logic? It's always something along the lines of "Of course I don't care about ______, but it would have been nice to be asked!" You'll find that even if they don't care what they're talking about, they feel good knowing someone was taking a genuine interest in them. You'll find out a lot about a person by asking them about their lives. Perhaps they are shy and cautiously present information in a way that reveals their fear of social rejection. Maybe they're very charismatic and charming, so they make their answer a grand story that captivates the listener. They could be deceitful, and they're answering a question with what you know is a lie, but you're playing it cool just so you can see how they operate. Perhaps they're completely full of themselves and regard your "interest" in them as another valueless drop in their bucket of self-contained hero worship... Whatever their personality, questions are a solid way to find out about them. Of course, I hope you're not asking this so you can get a free pass to start tuning people out... Even if you don't particularly care about the answer, you've still gotta be polite ;)
