What are some items that combine the use of electricity and magnetism?

I can’t find any items that combine the use of electricity and magnetism. I need every day items that people use all the time. This is for a homework assignment, but I can’t find anything on the internet on this. Thanks in advamce for the answers.
PS: I did ask this question in the homework category, but I haven’t gotten any answers yet. I put it in this section because people our age might know about this

The light is produced by the connection between electricity and magnetism. Is that correct?

Your friend goes on to say that light is produced by the connection between electricity and magnetism. Is your friend correct?

How is light related to electricity and magnetism?

Just need some information on that it doesnt need to be a lot just need some help on this i have to write three pgs. on light and its relationship with electricity and magnetism. homework

Compare Physics mechanics and physics C: electricity and magnetism?

I am currently planning on taking a physics class at a college next semester with the following description: covering calculus-based mechanics, thermodynamics, vibrations, and wave motion. The student will also perform integrated experiments dealing with the physics of mechanics, thermodynamics, vibrations, and wave motion.

I will already have completed calculus I by the time I start. I was wondering if I would be able to do that and independently study physics C: electricity and magnetism. Do you think it is too much? Will I be able to do them simultaneously? I want to do them both. Your opinion will be appreciated.

What is the difference between nRT and 3/2 nRT?

I had always thought the total kinetic energy in a system is PV = nRT, but today at school I saw someone say it was 3/2 nRT or 3/2 PV. Can anyone prove this and explain why PV does not yield the kinetic energy of a system?

My thinking was this:
PAd = some tiny work done by n moles of the gas, d is a tiny distance moved
v = Ad = tiny volume expanded or contracted
N/n = ratio between total moles and the moles that did work = V/v = V/Ad
total kinetic energy = N/n*PAd = V/Ad*PAd = PV

For Boyle’s law,what are the units? Can the pressure be atm, pascals, mmHG, etc. and voluem be Liters, mL, etc

In equation k=PV where k is constant in system

Hey! People I know the solution of our all energy problems and for rest of the world?

First go to this link, it’s an article on this simple technology: http://science.howstuffworks.com/energy-from-space.htm

So there is a solution for a totally clean energy for rest of our lives. And the cost of building could be repaid within 5 days of launching from the benefit we will get. The question why no one has still done it, and how can we altogether force of showy government to do it. We have answers, they are in front us. We have to do it.

The idea: Send big solar power plant into space. Which will work much more efficiently and always, since it would be always facing the sun. No clouds and nights to worry about.

Please support me in anyway you can, and make some effort yourselves to spread the word that we have a answer. This technology is not something new everything is understood about it. It’s like centuries old techy stuff.
sorry wrong link, Here is the correct link.

help with my renewable energy poster?

I’m making a renewable energy poster, and I want to work on it and finish it this weekend. I already have an idea of how to draw it out, and what goes where, but I would like some help with these areas:

- a simple definition of Clean/Renewable Energy
- why using that type of energy is good
- three facts on wind power, solar power and bio fuel power.

Also, what do you think of my slogan; “Cleaner Energy for a Cleaner World”?

Please go all out in your answers. I’ve done a lot of research into the area, but I can’t seem to condense everything so that it can go onto a poster and not be too overwhelming for the reader…especially since I found out the posters are going to be made into a calendar for 2011. Thanks!

Rate my Pokemon team?

Please read the whole thing. (:

Glaceon -
Water Pulse – for fire/rock weakness
Rock smash – for steel weakness
Ice Beam – I’d feel weird having an ice pokemon without an ice move
Toxic – debating putting this over quick attack haven’t actually done that yet, but it’s a free spot that has had other moves debated

Arcanine
Solar Beam – for the simple fact it pretty much covers its weaknesses…despite its a two turn attack, but I hope to have his hp/defense up enough to take a hit or two
Extremespeed – I don’t know if I spelled it right but yeah, in my opinion it’s pretty decent
Flamethrower – I chose it over fire blast for the accuracy difference
Dig – well, I didn’t know what else to put again and another fire move seemed a waste..but might change to will-o-wisp

Pachirisu
Grass Knot – for ground weakness
Thunderbolt – best 100% accuracy with decent attack I could find
Shockwave – I’ll probably change this later.. maybe breed in bite if doesn’t have to replace hidden power or this?
Hidden Power – eh, I miiiight change this one too

Beautifly
Giga drain – big weakness is rock, heals and hurts
Energy Ball – again, rock is a weakness, grass is an advantage and I can’t find any other moves that hold an advantage on the other weaknesses
Silver Wind – this and Energy Ball I might replace, we’ll see
Shadow Ball – again, might replace it, still debating some moves

Kingdra ehh, water and ice in same team seems not so smart but I wanted a dragon type that I liked, I’m picky about looks and work out mloves/stats from there
Dragon pulse – advantage on dragons, Kingdra’s weakness and the dragons weakness, go figure
Twister – dragon move, advantage on dragon, hits those using fly, not too bad
Flash Cannon – eh, steel type move(I think?), gets an advantage on few other types
Surf – well..best water move there was to choose from in my opinion

Houndoom
Crunch – I mostly chose him because he’s dark type, even though a few have dark type moves I might change though, I threw this in
Dark Pulse – two of the same move types in one? usually a waste, but like I said I chose for the dark type I have Arcanine for my fire type
Solar Beam – same with move repeats, usually a waste, especially a two turn one, but with next to no defense and this being the only attack to hurt weaknesses, I personally think it’s not that bad for the time being
Will-o-Wisp – Ok, ok, I’d feel weird with a fire type and no fire type move, and I did kind’ve want will-o-wisp in there..

Keeping in mind I have plans to add items, get them all to level 100 and max out stats, how does that all sound and what would you change?
Get rid of/change a Pokemon? Change an attack? Any item suggestions are appriceated. If I got anything wrong, I did this based off a site that I’m 90% sure is correct, please tell me.
Thank you. (:
And no, I’m not interested in battling, I still have to migrate/catch and build up, all that fun stuff.
I know I didn’t mention natures and whatnot, and I don’t know how clear I made it that I’m looking for mostly how the attacks and the Pokemon fit, (as in.. does the reason I have a move on a Pokemon make no sense because something is better? or, yeah) when I actually finish the team I can add details of stats and natures and whatnot..but nature/stats suggestions are appreciated ’til then if you aything would help with the attacks I’ve put it with.. as I said, I’m picky about looks, I am with moves too and I build everything after I’ve decided with those two and this time I wasn’t so sure. Thanks in advance. (:
Andd last thing.
I’m looking at all answers, I’m going to keep changing, I’ll ask again with final result, the stats and moves, etc etc..

To those who believe in evolution?

First off, let me be very clear: I am in no way, shape, or form a christian. I do however, believe that there had to have been some sort of a higher being to create the solar system, earth, human body, etc. So my question is, how can you believe something as far stretched as evolution, but absolutely refuse the possibility of a higher being. Let me give some reasons why evolution is far stretched.

“Sir Fred Hoyle a mathematician and astronomer calculated that the probability of one simple enzyme forming by chance is 10 to the power of 20 (one with twenty zeros behind it), to 1. Hence for one cell to form, about 2000 enzymes are needed, which makes the probability of the first self replicating cell forming by random movement of atoms as 10 to the power of 40000 to 1.”

The chances of that happening are the same as the chances of a tornado going through a junkyard and assembling a fully functional jumbo jet. (http://library.thinkquest.org/27407/creation/chances.htm)

I’m not trying to convert anyone to any religion or anything, I just want to know WHY you believe in something that takes such an incredible amount of chance. I mean look at the human eye. It is one of the most complex parts of our body, and if evolution were to be true, all of the parts of the eye would have to evolve at exactly the same time at exactly the same rate, otherwise they would seize to work. Come on, you wouldn’t put any money on a bet that had that sort of odds, why would you do it for what you believe in?
Let me also say, I know that disproving evolution does not prove a deity, I was just posing the question.

Second, evolution has not been proven by any means. And since when has religion not been allowed in school? I graduated last year and last I checked they were still teaching it. And that was in DC. So they are still teaching it. If you listen to teachers/professors/scientists talk about evolution, they say theory which means it has not been proven.
Thor is a loving god too: I like your answer the best. You shall receive Best Answer when the time comes.

How can I keep a Citizen (solar) watch battery charged?

My boyfriend has a Citizen (solar battery) watch that is continually losing a charge because he’s in an office most of the day, and the over head light isn’t sufficient. Has anyone else had this problem and found a solution or heard of a product out there that was created to keep watches like these charged? I’m thinking of a valet with some type of lighted feature perhaps.

English grammar/spelling check and rewording to improve help?

This is for a lab report for solar energy, I need some help editing it and rewording to improve.

Of course, solar energy has a lot of benefits but also has some disadvantages, but of course nothing is perfect. First, we will look at the benefits of solar energy. Solar energy gives off no pollution since it does not release nitrogen oxide, carbon dioxide, sulfur dioxide nor mercury into the air. Moreover, it does not burn fuel nor does it generate emissions. Solar energy is renewable because the sun’s rays will never run out whereas other types of energy such as coal, natural gas, propane, gasoline, wood, and nuclear energy are non-renewable. With solar energy, you can make money even if you are not leasing your house, many markets, solar companies may be willing to lease your roof/land to install their solar installation. If you install the solar energy yourself, you can save a lot of money, which ofcourse is just as good as making money. Solar energy is plentiful since the sun will be around much longer than oil, gas or coal will be and the basic elements used to make solar cells such as Silicone which does not decompose but is recyclable and aluminum does not decompose but is recyclable and can be recycled over and over again. The sun is out around 12 hours a day, and in a whole day there are 24 hours. 12 hours out of 24 hours is half the day which would give people a good deal of time to capture energy. By using solar energy, people can catch some of that wasted energy and convert it into something useful which can be then stored and even sold to your local utility supplier for a pretty good profit. Solar energy is extremly viable and you need not worry about replacing anything for a long time and most solar panels come with a performance guarantee from 20 to 30 years. And lastly, as much as 90% of export income of some developing countries used to pay for the importing of oil when most of that imported oil goes to power generation. By using solar energy, the export income could be used for investment in a better health, education, industry and economic development. Now, we will look at the consequences. The most obvious consequence would be the sole dependence on the sun which means that you either have to have an alternate source of electricity or have some stored. Then, the primary costs, are high. Moreover, solar panels require quite a big area for the installation to achieve a good level of adaptability. And lastly, installation of solar panels may be restricted by local bylaws and in heavily polluted areas the full value of the energy that the sun creates will be decreased. As you can see by the above there are abundant benefits of solar energy but there are also consequences. If we were to weigh the benefits and consequences, I would say that the benefits far outweigh the consequences.

solar flare vs asteroid impact:Please read be for answer?

Which has more energy and is more powerful,a solar flare with more energy than a billion 100 megaton nuclear bomb,or a asteroid the size of texas moving at 134,000 MPH.Can’t you think of a 100 megaton nuclear blast,but a billion of them going off at the some time,(the largest nuclear blast was at 58 megaton and look at how powerful it was and what it did)And o boy the asteroid impact,this is just way to powerful,i have read that a asteroid 18 miles wide moving at 67,000 MPH would just be to powerful to add up,but try to think of a very high yield megaton nuclear bomb going off ever second for more than 6,000 year and compress all of that into one giant blast, think of how much energy that is on impact,how powerful is that,i love natural disasters of all kinds and i like to talk about them all please email at (bowlingkingred@yahoo.com)sorry about the long question i write.

Help please if you can?

Can u help me please? I need to find out facts on wave nergy like what effects it has on people and places, or how much energy it uses anything will be helpful. I typed it in yahoo and it always come up with solar energy – not what im looking for.

Seeking sincere friendships in 2008…?

My name is Don and I’ve been in a situation that I resolve to change above all other resolutions. I’m 42-years of age, 5’9″, 140 pounds, with blond hair and brown eyes. I am musically inclined and play, write, and sing it and listen to Yahoo! Launchcast plus during the day. I’m a small business owner and enjoy what I do. I am science-minded and am well versed in physical science including climate change and climatology as well as alternative (solar) energy. I’m turning knowledge of the latter into a company division by June 2009. I may be knowledgeable, but I am neither a nerd or a geek and love working out as well as wearing tight blue jeans and a black leather jacket. I have and made no friends in 2007 and I resolve to change that in 2008. So if you would like to know a man of wisdom and a man of peace, then I seek you out for friendship! I use Yahoo as my IM and have VOIP headphones to chat as well. Happy New Year!!!

How many explosives would it take to disrupt the rotation/revolution of Earth or blow it up? Cosmic Power?

I heard that dropping all our nukes on the Earth wouldn’t do anything to the rotation of the Earth. Similarly all of the explosives on earth can’t put a dent in the sun?

From a yahoo user: “Sorry to disappoint you but with 50,000 nuclear weapons world wide with, say, an average of 5 megatons each (a high estimate) – you get 2.5 x 10^11 tons of TNT or 250 gigatons of TNT. The largest quake registered, the 1960 Chilean quake, released almost 60,000 gigatons of TNT equivalent. Did you feel the quake?

Probably not. People like to think they are important and powerful. A ton of TNT is about 4.2×10^9 J so all of the bombs will release about 1.1 x 10^21 J in a few seconds and then it is over. That number is 1.1 zettajoules. The total solar energy absorbed by Earth’s atmosphere, oceans and land masses is approximately 3,850 zettajoules (ZJ) per year.”

What kind of power would one need to obliterate Earth? It seems impossible.

What is a bio-diesel generator?, Wave energy, And.. (look at extra detail)?

What is a bio-diesel generator?

What is a ‘Terminal’ in this sense .. ”Galapagos’ main airport will have solar panels to meet a quarter of its power needs, and a terminal that uses the wind for cooling.”

Also, what type of renewable energy source could be used for the rain?
Like Solar Panels are used with the sun, Turbines used with the wind…

And what is Wave energy? Like how does it work?

Energy’s in a Spacecraft?

This is for my little brother. He needs help with this question:

Describe the energy type sources used in a spacecraft?

I told him there could be Solar Panel fitted to acquire energy. Couldn’t fink of any other types or sources. So if you could tell sum more it could be great.

What type of diode should I use on a small rc car?

Im converting a rc car (about 1 1/2 feet long by a little less then a foot) to use solar energy. Im using a 12 volt solar panel for the power what type of diode should I use??? please help
I have moterhome diodes would these work?

What type of energy are these?(10 points!)?

Solar Panels
Wind turbines
geothermal energy.

Its confusing me

Is this reasonable or surprising? We find a planet in another solar system that had Earth like plate tectonics?

; the planet is the size of the Moon and orbits 1 AU from it’s star.

Reasonable or Surprising? Make Sense or Absolutely impossible?

Please Explain.

How do you make a home nuclear generator to power electricity?

Hey. I am tired of paying the electricity bill and got fined for taking my neighbours from his pond. Turned out he never watched tv or had a computer. When his bill went from £10 a month to £150 he got suspicious and found the cable and adaptor that I had connected to his fish pond in the back garden. Anyway thats another story. I did bury the cable but obviously he unearthed it.

I know some people use solar plates to provide electricity for their home, but this costs too much. I don’t have £25.000 to spare for this stuff. Also it is a rented place so I don’t even own the roof.

I was thinking of a nuclear generator that I can build at home and use to power my electricity usage off uranium or something. I am really good with building gadgets, and know where I can get weapons grade uranium from cheap. I just need advice or a walkthrough on how to build a mini nuclear power plant in my own kitchen.

what is the average efficiency of flat plate solar collector?

what is the minimum cost of solar plates for domestic use?

i want to use solar plates for house hold purpose which can give power for 3 tube lights,2 fans.1 tv,1 refregirator. please tell me the price range

who to make small solar energy for PC?

Who to make small solar energy for home PC. please help me any one. thanx a lot.

Are there any programs to fund solar energy for home use ?

where do i find info for solar energy for home heating and other uses?

What are engineering challenges to develop solar energy for comfort/home uses?

What are engineering challenges to develop solar energy for comfort/home uses?

Do you think viable fuel sources are being withheld because they haven’t figured out a way to charge us for it

Things such as wind, solar and similar methods of alternate sources of power.

There are tax breaks for people interested in it, why not take the tax breaks from dirty fuel producers and use it to get people to use clean alternatives?

This will lower our dependence on other nations and force the dirty fuels to clean their act…

Would you be willing to power your home with wind or solar power if it were easy to obtain and cost efficent to operate?
Shouldn’t this be a major politicial issue?

Who doesn’t have an INTEREST in Oil?

The Administration is upset about a Louisiana Judge over ruling a lift of the Oil Moratorium, The media saying he has an interest in the oil industry.
OK WHO doesn’t have an interest in OIL, If you have a car or a job YOU ARE dependent of oil.
All those YAHOO’S out there that are against this and are for ALTERNATIVE ENERGY have you ever looked into the electric cars? How efficient are they? Or how about Solar Powered Homes, for the average home it would cost you approx. $ 30,000.00 + just to get started….So you tell me How can We not have an interest in oil???
Now is not the time Mr. President….Sorry
Let’s keep the wells drilling until we can come up with a way to NOT make our utility NECESSARIES skyrocket.
Whats your thoughts?

please help me on this issue ?

my monthly is $300 and cost to power home by solar panels is $95000. so what to do go for solar panels or stay with monthly bills of elasticity ?
every solar thing is costly look at this keyboard which is solar $71

http://www.logitech.com/en-us/keyboards/keyboard/devices/k750-keyboard

and you will not believe the price of solar LCD computer monitor is $1500.

but my father saying me to everyday to make home solar powered.

What items or materials will I need to make a set of solar panels to power a few appliances?

ok i know that solar panels dont create a huge amount of power but i was looking to do this as a little home experiment.

So i know that i need solar panels i can get them off eBay but what else.

1) Solar Panels
2)Charge controller
3)Tabbing/Bus wire
4)…

Please give a list of items i will need so i can try to find them so i can get an estimated cost together for some POWER!!

Thanksyou all.
