I'm modifying my xbox 360 by adding additional fans into the 360. The current stock fans (2 fans) run at 9v. but is rated for 12VDC. I'm going to add two more 12v. fans. I have found different 12v. sources on the motherboard.

My ideas are:
A. solder all 4 fans to the 12v. source for the DVD drive
B. solder all 4 fans to the power supply plug on the motherboard.
C. power by installing a open circuit jack for 2-conductor plugs and using a 12VDC/800mA adapter

The Xbox 360 power supply provides 203 watts, and 12v DC current at 16.5 amps, and 5v DC at 1 Amp.

Would the four fans combine take too much power away from the 360? Please let me know what might happen if I choose A or B. Thanks!

Sulfuric Acid may be produced by the following process:
4FeS2 + 11O2 --> 2Fe2O3 + 8SO2
2SO2 + O2 --> 2SO3
SO3 + H2O --> H2SO4

the right answer is 20.00
please explain why this is, and please also list the steps that you took in order to get the answer

Everyone loves to talk about gravitational waves, but it's just too weak of a force and too tied up with our sense of space-time to really be measured...

So has anyone really done measurements on the propagation of large-scale changes of a straight electric/magnetic field?

In my sillyness I imagine some scientist in the pacific ocean turning some massively strong electromagnet on and off @ a predetermined frequency and some other scientist sitting in the atlantic ocean with some incredibly delicate and sensitive field indicator expecting to measure disturbances at the predetermined frequency by some time offset that hopefully makes sense given all that we know about field interaction and relativity.

Tried to find information on this through normal noob-y means (wiki, google) and failed so I ask here.

I dont understand how to calculate the number of protons, neutrons and electrons. It says calculate the number of protons,neutrons,and electrons, in a. 13 is in the top left and 17 is in the botton right then it has CI, then 23/top left 11/bottom left and then Na, then it has 84/ top left 36/bottom left Kr. I have no idea what i am doing, i have never taken chemistry in my life so if anyone could break this down it would help me with the rest of my problems. Thanks!
