I heard that two flat conducting parallel plates have the property that electric field at any point between them, is uniform, and of constant magnitude. I was wondering how this was possible. For example, a test charge closer to the positive plate conpared with a test charge closer to the...
i heard that a faraday cage is often used in shielding e.g. sensitive electrical equipment. I was just wondering, because, in http://socrates.berkeley.edu/~fajans/Teaching/cartoons/Shielding/TestChargeShielding_files/frame.htm
it seems that the electric field is not zero at ALL times. i.e...
If I want to determine the motion of the plane, with respect to the Earth, is its motion = 50m/s - decel due to friction force? or from here, do we still ahve to take into consideration the motion of the barge?
From the Sir Isaac Newton contest:
A 1.0*10^3 kg plane is tryin to make a forced landing on the deck of a 2.0*10^3 kg barge at rest on the surface of a clam sea. THe only frictional force to consider is between the plane's wheels and the deck, this braking force is constant and is equal to...
The Feynman Lectures on Physics including Feynman's Tips on Physics:
how are these books for physics training. i am thinking of buyig them. how much help r they for ipho training? thanks!
I'm sorry..I think I didn't explain my situation well enough. I am asking, in terms of say...
suppose we have a heating element submerged in water. (e.g. a coffee maker, or amny other possible everyday things). When the current is passed through the nichrome heating element, will the current...
so, say a circuit is submerged in the water. The circuit requires only a 0.83V to ionize the surrounding waters?!? Wow! I though it wouold be much higher than that!
