---------- About Mechanics waves ---------
We know that in mechanics waves, energy is proportion to Amplitude^2.
So we can write equation as E = kA^2 , where k is a constant.
Is it possible to find this constant (k) ?
Is k different in other waves (meaning it is depended on other...
I've checked. For the first system, there is four choices:
1. 2DOF
2. 3DOF
3. 4DOF
4. 6DOF
For the second system, it is writing test.
Anyway, Please ignore the choices. The choices are usually incorrect.
No other instructions were given in this exam.
I'm currently in high school and never learn such these theorems. I know only DOF is how many axis the object can move/rotate. (Of course, my friends know nothing) Wikipedia and many website do not give enough information. Could you please...
Anybody please ?
Maybe I didn't give much information about variable.
R = radius of the pulley
k = spring constant (I don't think we really need it)
M, m = mass of the object
This is not really the homework. It is the university examination problem. The problem here is many teachers/professors answer differently and not much detailed. And we don't know who was the exact professor who create these problems.

About Pilot Wave ?
I found this on wikipedia. http://en.wikipedia.org/wiki/Pilot_wave#Principles
So is my second hypothesis right ?
"Although we can not measure/predict anything exactly, everything is certain."
Still not sure about this correctness from wikipedia.
Thank in advance for many...
Thank you very much for fast reply
"no particle has a 100% definite position and momentum at any point in time"
I'm not sure about this (need some more explanation)
All I've read, HUP only told me that we can't measure two values exactly at the same time. So if we don't measure momentum, we...
Greeting to everyone. This is my first time here (A bit nervous)
According to many sources, many books, "Heisenberg uncertainty principle" tells us that it is impossible to measure anything exactly. I agree as the proving equation does not apply any measuring instrument at all which means...
