    High School Radio Waves: What Can & Can't They Pass Through?

    yes, you ask reasonable questions. If you can imagine an open door, with glass uprights and lentil, surrounded with wooden walls and concrete superstructure. Every kind of electromagnetic radiation (all kinds of light) are attacking each mass at the same moment, the dense matter such as concrete...

    High School Radio Waves: What Can & Can't They Pass Through?

    As far as I am aware, wavelengths determine that which they can pass through. For example. microwaves are pretty small, hence the word, micro... and can't pass through the mesh you'll see in your microwave window.. (the gap between each crest)... the odds, likelihood, is that they will hit the...

    Undergrad How to find charge given voltage?

    also, talking physics with english is probably better than latin or greek :) :) :) biology and chemistyry is clearly classical and as for maths? yeah who cares.

    Undergrad How to find charge given voltage?

    Ahh, he asks a very real question... It is easily answered but still has a real application... It's a quantum fusion decision, me thinks,.. but as far as this world is concerned, I'm thinking a superconductor is the closest you are likely to get to an answer.. Perpetual motion perhaps? Who knows...

    High School Centrifugal Force: Is it Radially Outwards?

    yeah, that makes perfect sense.. but it would be a good idea to make sure one knows the difference between the two before confusing the reasoning and theory. Centripetal is the vector force (curved or lateral direction) and cetripetal is the inertial force (the tangent).. can't really be arsed...

    High School Centrifugal Force: Is it Radially Outwards?

    besides... that would be centripetal force, not centrifugal.

    Graduate Is Time Variable When Light is Constant?

    Yeah okay I have read father Janus and heeded to his judgment. The grounding of basic physics is a must and if you are looking for fact then it's best you look at other posts. Considering that a person is moving, faster than another; One an only deduce through empirical evidence that as far...
