24 litres of air (at RTP) will contain 1 mole of gas. You are told that you have 12.9 cubic kilometres of water vapour. Convert this to litres, and then to moles The enthalpy of vaporisation of water is 40.65kJ/mol,  so you can now work out the total energy released.\nYou would also need to research the power consumption of a city of 1 million people!

Well, if this must have something to do with Math, or abacus calculation, I suggest that you have these slips of paper having equations, like one slip will contain the "question" and the other will contain the "answer".\n\nFor example,\n"3 x 72" and "216"\n\nMake up a few different equations with such slips. Then, in your class, hand out these slips to the children. If they have the "question" slip, their task would be to find the person holding the correct "answer" slip and vice versa.\n\nThis will allow them to interact with one another in some sense. Hope this idea isn't too dull!

I hate my son's middle school homework, too.  It's not like the problems I had in my day.  The answer to this kind of question is something like I wrote below.  \n\nThought:  Looks like a subtraction problem.\nInfo:  Start time and duration.\nPlan: Write a math sentence or equation.\nSolution: Answer

Sounds like a homework question, and someone is at a losss for ideas.

Good luck with the homework

Do your own homework. How do you expect to learn if you can't do it yourself?\n\n My appologies, I feel mean now.

hmm im not quite in college yet, but i hope to be help.\ndo you know the values for f, h, v, and a?\nif you do, id substitute it in.\nthen square both sides. \nand then solve.

Use the following to help solve this problem:\n\ni ^1 = i\ni ^2 = -1\ni ^3 = -i\ni ^4 = 1\n\nThis pattern then repeats:\n\ni ^5 = i^4 * i = 1 * i = i\ni ^6 = i^4 * i^2 = 1 * -1 = -1\n\netc.\n\nSo to solve any i ^n, just look at the remainder of n/4:\n\nremainder \nof n/4 ....... value of i ^n\n- - - -  - - - - - - - - - - - - - - -\n0 ....................... 1\n1 ........................ i\n2 ....................... -1\n3 ........................ -i\n\nSo now let's tackle your specific problem:\n\ni ^16 = 1 (since n=16, n/4 = 4 with remainder of 0)\ni ^6 = -1 (since n=6, n/4 = 1 with remainder of 2)\ni ^5 = i (since n=5, n/5 = 1 with remainder of 1)\ni ^13 = i (since n=13, n/4 = 3 with remainder of 1)\n\nSo, i^16 + i^6 - 2i^5 + i^13 = \n1 + (-1) - 2(i) + i =\n-i\n\nHope that helped!\n\n~ ♥ ~\n\nPS -- The "2-i" answers are incorrect.  Those answerers just made a tiny typo and took 1 - (-1) as the first two terms, rather than 1 + (-1).  Just wanted to let you know, so that you don't put the wrong answer down on your homework.

Why are you failing?  Because you hate doing homework or because your ex is bothering you?\n\nIf it truly is the latter, ask the teacher for a seat change.  If the problem is really bad and that does not help, ask for a different math class.

Follow the method from the other 4 problems that you just posted.\nIn order to learn, you have to try things yourself.

Umm... I think a "web math homework solver" doesn't exist. You could try getting Mathematica (i'm not discussing how you get the full version), it is a little complicated but it solves (if you know how to use it) all kinds of math problems.\n\nhttp://www.wolfram.com/

I've just set up a forum to help with any kind of homework.\n\nhttp://s9.invisionfree.com/Homework_Help_Circle/index.php?act=idx\n\nIt's free to join but i'm a bit lacking in members at the moment.

Is this your idea of Homework Help??? Obviously, no one was interested in helping you plagerize someone else's effort.  I certainly am grateful for that.\n\nDO YOUR OWN HOMEWORK!!!

this question is wrongly put in this forum. This should be in the homework forum. And you will do yourself a favour by solving that problem yourself. Trust me, it teaches you a lot about how to synchronize stuff.

Sounds like a homework question

Someone might help you do your homework but you will find it hard to find someone to do your homework. Give it a shot and then ask for someone to look it over.
