Question by Amine: How far do you have to stay away from a 1000 watt microwave in order to not get radioactive waves from it?
Wow that is a long question i only had 4 characters left over. Does anyone know?
Best answer:
Answer by billrussell42 You can stand as close as you want.
There is no “radioactive waves” emitted by a microwave oven at all. what is emitted is microwaves, a form of radio or RF waves, and that is blocked by the wire mesh in the door.
I don’t think there is any such thing as “radioactive waves”. You can have radioactivity (but not a microwave oven) but it is not considered a wave.

Question by Daniel Aureli: Statistically comparing the power usage of a 500 watt refrigerator to a 100 watt lightbulb.?
A company claims that its 500 watt refrigerator uses less power than a 100 watt light bulb when they are both constantly running. What is the best statistical method to use to compare data gathered on the power usage. I was thinking Hypothesis testing. I would really appreciate your input on what evaluation method would be most accurate. Thank You.
Best answer:
Answer by cidyah Yes, hypothesis testing is OK. You need a random sample of refrigerators (some with power greater than 100 watts light bulbs and some with less than 100 watts light bulbs).
The parameter of interest is the amount of time when they are both constantly running.
H0: No difference in time regardless of what light bulb is used
HA : Bulbs with power less than 100 watts runs the refrigerator longer.
Your sample mean should reflect what you hypothesize. If the mean time is not more with less than 100 light bulbs, you should change your alternative to a two-tailed hypothesis.

www.windynation.com | This is a very short video demonstrating the power potential of our 500 Watt wind generator PMA. The PMA is hooked up to a 3 phase bridge rectifier (converts 3 phase AC to DC) and the DC output is connected to a 60 Watt (12 Volts, 5 amps.) halogen light bulb. The video speaks for itself. You can tell from the video that the rpm’s of the PMA are not that high and it is still able to crank out 60 Watts with no problem. Imagine what this thing can do with a 15 mph wind and 30 inch blades. This is a great and affordable wind generator PMA. Our PMA’s and other wind generator products are available on ebay (seller id windy_nation) and windynation.com
Question by atomicrebel@rocketmail.com: best way to wire dual 12″ 1,200 watt subs and a 500 watt amp?
A couple days ago, i received some Visonik VPB212PK Dual 12″ 1,200 watt subs (I know, beginner subs) and the matching 1000 watt amp from a friend. I’m wondering what the best way to wire the subs to the amplifier is. I am planning on upgrading to a lot better subs when i get the money, but for now this is going to have to do. I purchased a 4 gauge wiring kit because my friend kept his wiring kit for his new subs. I don’t have any of the manuals or anything, but on Amazon it says the subs are 1,200 watt peak (600 Watt RMS) and it says the amp is 1000 watt peak ( 500 watt RMS). The amps features are supposedly 1000 watt peak output at 2 channel bridgeable, and 1 channel 500 watt RMS. does that mean I should wire them with 1 channel at 500 watt RMS? That sounds to me like it’s the better choice because it’s outputting to the amps actual RMS. If that’s the case, how do i wire both subs to one channel? I’ve clearly never wired subs before and any help you can give is much appreciated! Thank you very much.

Answer by Charles do yourself a favor and buy a good wiring kit,the rest of that stuff your talking about will give you many headaches.but if your going to use it for now go with 4 ohm load and buy good rca cables with the good wiring kit.and put a cur.breaker or a big fuse about a foot off the wiring from the battery to the amp.this is the hardest part of the job running wire and hooking it up right. buy a good wiring kit and rca cables so they will work when you get some better equipment.go to best buy and pick there brain.better equipment is sold on ebay new and used.take a look, car audio.if you dont have a clue dont do the wiring .hire a pro.you can burn out your cars comp if you dont know how to wire this equipment.
