Interesting. So if you think that you made some amazing discovery protec your intelectual property by publishing it in some officila science magazin. Of course editors or profesors are people who will examen your paper and ideas and give their jugment on your work. Lots of luck especially on rough parts

In my oppinion it would be a shame and unfortunate for menkind to dissapear. Beside our destructive behavior and all bad influace we have on everything living around us, we still accomplish so much in such short notice of say 10.000 years in wich we envolve to a moder men. Of course our sun will swallow the earth in 3-4 billion years and kill everything that crawls in 1 (or even less) years but it gave us so much till now and will give enough time to think over some solution for survivel. Somebody or something invested a lots of efforts making all this interestig puzzles to be cracted. It would be real pity nobody to obtain that long homework all the way thru. So everyone start brainstorming ideas for new outer space human colonies

Hm looks simple but it could be tricky...As for the first question you should be looking mesaurment of gravitational field that exist in the center of asteroid B. You`ll be able to do that by using superpositotion model. Calculaton of force should be easy afterwards if you have knowlage of gravitational force vectors. However you have to asume that the problem is static and to insure that you are determining vector of force in particular moment (for istance t=0) cause if they are moving and have some values of speed then calculs of force in fuction of time becomes a lot harder.

Long time no see thermodynamic equations... I'm little bit rusty. However it seem to me that everything is correct. Fine example of diesel cycle.
