Electroencephalography EEG is an electrophysiological monitoring method to record electrical activity of the brain. It is typically noninvasive, with the electrodes. Electronics for Absolute Beginners, Study Guide, Chapter 1 2. Steps. Now for this experiment we will demonstrate that Opposite Charges Attract, and Like Charges Repel. For this experiment, you will need 2 balloons available at Walmart by the card and party section for around 11 unsuspecting pet or sibling or if u want to play risky, 1 unsuspecting stranger.

No, Im not suggesting that you kidnap the kid, I mean beat the kid in a game of rock, paper, scissors to win the balloon. After youve acquired and fulfilled all of the pre requisites, you are now ready to follow these steps. Step 1.  Pump air into the 2 air balloons. I dont care how you get air in there, as long as it is legal. Step 2.  Acquire your target. If youre a loner like me, that will be yourself. Step 3.  Aim for the head. Step 4.  Rub 1 balloon furiously on the targets head for 4 seconds, or if it pleases you, keep on it until your arm hurts. Lr_cc_app_noshadow_RGB.svg' alt='Tutorial See Electrical Expert Pdf 7' title='Tutorial See Electrical Expert Pdf 7' />Now, what do you observe Does your hair stick to the balloon If it does not, its the balloons fault, repeat Step 4. If it still does not stick to your hair, then youre probably bald. If your hair does stick to the balloon, congratulations, you just won yourself an explanation Remember when I said generally materials are balanced or neutrally charged has the same amount of protons as electronsWell, it just so happens that your hair and the balloon are neutrally charged prior to you rubbing them with each other. When you started rubbing the balloon with your hair,  your hair lost the electrons to the balloons with the aid of friction. Now, this means that your hair is no longer neutrally charged, because now its electrons and protons are no longer the same quantity. The balloon stole the electrons from your hair, which means now you have more protons than electrons on your hair, and this makes you positively charged. Remember in math when the positive number is bigger than the negative number, if you combine them together, the answer would be positive Well, the same principle applies to your hair, now that the number of protons positive is bigger than the number of electrons negative, when combined, the result your hair becomes ultimately positively charged. Okay, so we got that down, your hair is now positively charged. Okay, my explanation is only half way there, so bare with me. Heres the second half. Well, because the balloon acquired the electrons from your hair, now the balloon has added more electrons to itself. This means, that the balloon now has more electrons than protons. This means that the balloon is no longer neutrally charged, because remember what neutrally charged means Youre right, neutrally charged means, that the material has to have the same amount of electrons as protons. Well, obviously the balloon fails to meet that criteria. And because the balloon has more electrons negative than protons positive, it is now considered negatively charged. It behooves you to remember, that in math, when combining a bigger negative number with a smaller positive number, the answer becomes negative. The same principle applies to the balloon, now that the number of its electrons are bigger than the number of its protons, when combined, the balloon becomes ultimately negative. Okay, now, so we got that one down too, the balloon is now negatively charged. Okay, so let me get this right, the hair is positive and the balloon is negative Goodness gracious, thats why your hair is attracted to that balloon And yes, if you remember, the rule Opposites Attract, that is why the balloon and your hair are drawn to each other. Okay, now, now, calm yous a. Weve only proven part of that rule, we still have to prove the other part, which is like charges repel. To prove that like charges repel, you have to repeat Steps 1 through 4. And then follow the steps below Step 5. Tie each balloon with a string, then tie their strings together as demonstrated in the image provided. Pes 2009 Full Version For Windows 7. Step 6.  Hold the balloons in front of you while making sure that theyre not touching any surface. Now, assuming you did not pump the balloons with helium, the balloons should be hanging down towards the floor. Now, what do you observe Well, heres the explanation for that. Remember, that the balloons after going through steps 1 4 became negatively charged. Well, now what youve got in your hand are two balloons that are both negative, that is why they are avoiding each other like a plague. Because remember the other rule Correct Like charges repel. Now go on your merry way and have a soda can race with that balloon.
