What does my teacher want me to do with this problem?

The answer, interestingly enough, is not zero.    ( In the following 3 E 5 means 3 times ten to the fifth...   3 followed by five zeros. )  \n\nOxygen and carbon in the air get cycled in and out of plants and animals, burned in fires, etc etc.  But in general the Nitrogen just hangs around. \n\nThere's been plenty of time since cesear for perfect mixing, so we can ignore that....  \n\nNitrogen is 80% of the air...  but for the purposes of this discussion, let's ignore that too.... \n\na breath is between 1 and 2 liters, but let's go with 1 since it simplifies the math. \n\nWe can pretend for the purposes of discussion that the air is about 5 kilometers thick...  or would be if it was all at one pressure. \n\nand the surface area of the world is   5 E 8 square kilometers. \n\nso, we have 2.5 E 9 cubic kilometers of air, or 2.5 e 15 cubic meters, or 2.5 E 18 liters of air around the earth. \n\nSo, each of our breaths uses 4 E -19 of the earths air.  \n\nNow, go back to that last breath of cesear's.  \n\nRemembering the definition of a mole, 22.4 liters of air contain 6.023 E 23 molecules of the stuff air is made of.    So, one liter contains 2 E 22 molecules of air-stuff \n\n2 E 22 times 4 E -19  gives 8000  (8E3)  -- and most of that diatomic.  Throw away 20% (the carbon and the oxygen and you get 6000 nitrogen molecules, or 12000 atoms \n\nor there abouts.  \n\nThis is a classic "fermi question" -- useful for developing estimating skills

keep track of your grades, then if he tries messing your grade it wont work.\n\nbut seriously, i really dont think this teacher would TRY to make u fail, unless u are really disruptive and annoying to him, even then he probably wouldnt.

"Why do teachers give a load of homework and projects?"\n\nTeachers give you a load of homework and projects to educate you in that field of study. You'll be suprised at what you could possibly learn or become, and realize that you are fortunate to even recieve an education. So quit your complaining and count your blessings.\n\nAlso, I reccomend you focus a little more on that english homework of yours, okay?

How do you expect to learn something if you get others to do your homework.  If you do not know how to do something, you should go to your teacher and ask him to explain it further to you.

Explain the situation to the school computer administrator.  It is probably one of the technology teachers.\n\nIf that doesn't work, use a computer in the public library.

Go to a teacher to show you more cases, and try to work harder!

If you were in school-you should ask your teacher what he/she requires.

Send another email apologizing for the mistake and explain to him that it was not meant to go to him. If your teacher does not bring it up say nothing.... let it stay an unspoken embarrassment. It is not that big of a deal. If he brings it up just stick to your guns and apologize for sending to him by mistake. Don't go overboard with the apology though, the bigger of a deal that you make out of it, the bigger of a deal it will become. If this teacher changes the way he treats you or brings up the mistake on a regular basis be sure and report the situation to the proper administration officials at your school. Good Luck.

Pay attention in class. Jot down what you don't understand and ask them later if timer permits. Also, listen carefully if the teacher already answered one of your questions.

ask your teacher what he reccomends.

You should probably go see your tutor at school for help.  You never know what kind of answer someone is going to give you...or if they are just messing with you.

Ask your teacher, I have no idea what that is.

Sit down with the Principle of the school and discuss the problem.  It is in the school's best interest to find resolution to the problem, plus they have information that can help bring the matter elsewhere should the problem persist.

What is it specifically that you are looking to help her with?  I am a grade 6 Language Arts teacher, you can contact me here if I can be of some help to you.

I would tell the teacher. But your partner may deny it so be prepared to stand your ground. I mean why should you fail just because your partner is too lazy to actually do the work?

Ask one of the teacher's for help.

Only you and she can really know the answer to this question. Why don't you speak with her? Tell her what you'd like to be able to do and ask her why you are not allowed to help others, particularly if you are her "assistant"\n\nSigh. Thumb trolls strike again. My answer is a valid possible way to handle the situation. Talking with the teacher is a good way to try to resolve the issue.
