Which is true electric current running along a wire can be used to produce magnetic force or moving electrons through a magnetic field can produce an electric current?
They're both true, but I'm not comfortable with the way they're stated. I would have said: -- Electric current through a wire produces magnetic force. -- Moving electrons constitute an electric current, whether or not they're moing througha magnetic field.
What color of light best passes through blue glass?
blue light passes through best. my knowledge of light is limited (while googling iti'm simultaeniously answering this question) however, i do know that in THEORYONLY blue light should pass through a blue filter. only red light will pass througha red filter. only teal light will pass through a teal filter, etc, etc.===========================And here is a revelation that may blow your mind ... you may want to sit down:How do you suppose it comes to be known as "blue glass", eh ?The glass looks blue because when light of all colors pours into one side of it, onlythe blue light comes out the other side. Any other color is absorbed in the glass,and is never heard from again. The result is ... presto ! ... the glass looks blue,because that's the only light that's left to travel from the glass to your eye.

How Do you fix a Kia Sportage 4 wheel drive 1997?
buy a manual lock out hub kit from an online source - not Kia made because they cost so much but you can find one online througha google search. The problem with 1996-2000 Kia's is that the vaccuum seal for the 4x4 lasts for only a minute - go to a lock out system and you will never have a problem again with 4x4
Why does the violet light split into different colors when it passes through the prism?
Violet light does not split into different colors when it passes through a prism.If it goes in violet, it comes out violet.White light is a combination of light of many colors. If you pass white light througha prism, a spread of different colors will come out of the prism, because each colorbends through a slightly different angle on its way through the prism.
What effect does energy have on a resistor?
One way to look at the purpose of a resistor is as a device built to dissipateelectrical energy. Some (but usually not all) of the energy of the current througha circuit is always dissipated when it flows through a resistor. The energy lostleaves the resistor in the form of heat.The number of joules of electrical energy lost and heat dissipated by the resistor is(amperes of current through the resistor)2 x (ohms of resistance) x (seconds of time it continues)If you work with resistors often, or see several of them inside an old radio, you noticethat there are physically big ones and physically small ones. The size of the resistorisn't related to the number of ohms of resistance it has. The physical size is relatedto how fast it can dissipate energy (heat) without melting or burning up. A biggerresistor has more air around it, so it can get rid of heat faster.
