where do ants, flies, butterflies, frogs, snakes, and all those other mini-wildlife go in the winter? My sister says underground but I don't see how that's possible, except maybe for ants & snakes. It's not like you'd ever see a butterfly in the snow, so where do they go?

and said that if we can finish this we should be ready for our final coming at the end of the month. The problem is these are super-hard.

Can you guys out there shed some light on them.

ps: Don't worry about Problem A. I solved that It is an interesting one

I am interested in issues directly related to the oil and gas exploration and production. Of course, the first task is to identify which problems need to be solved. I will be more than happy if I get specific answers about issues that affect the oil business and that are yet to be solved.

I'm having difficulty with triangularising square matrices. Unfortunately the lecturer ran out of time today, and so wasn't able to do any examples of how to triangularise a square matrix, and I have some work to hand in tomorrow and am very stuck! I would really appreciate it if anyone could give me an example of how to triangularise a square matrix, or if you could recommend any websites that show how you would go about this.

I need to know what is the meaning of force how it works and what it measures in. Also what are the definitions of dynamic and static friction and how is this realted to force. e.g how much force do u need to put in something with X amount of friction. The teacher said something about dynamic friction minus static friction but i did not underdstand? plzz helpp
