Just to be be clear about what I am asking, I would like to ask a few different questions 1st:
Are these assumptions correct:
1) In DC, current flows through a circuit due to the movement or flow of electrons. So in a DC circuit anyone electron will do a complete lap ( or circuit ) of the...
We all understand what metres PER second (m/s) physically means... but,
What I was wondering was what does a 'metre-second' actually mean? Or does it have a physical meaning at all!
As an example:
If we take the units for Dynamic viscosity we have:
Kilogram per metre second ( Kg /...
A friend posed this just for fun but now its really annoying me.
how do you divide 90 into three parts so that each part is 1.6 times greater than the last.
i.e: the second value should be 1.6 times greater than the first and the third value should be 1.6 times greater than the second?
Im...
HI,
Firstly I'd like to open with I know what an electron is and I know all about its charge and the role it plays in electricity, current, free electron model etc etc.
My question is what is an electron 'made' out of? My reasoning is that it can't be made out of anything physical as its...

I have to measure the end point energy of a beta minus particle being emitted from a Sr-90 radioactive source. Part of this is plotting a Kurie plot. I am using a pulse height analyser (PHA) to get the beta spectrum (which counts how many beta particles are detected N,on the y-axis and...
Diamond has a Debye temperature of Dt = 2000 K and a density of 3500 kg/m3.
The distance between nearest neighbors is 0.15 nm. Determine the velocity of
sound using the Debye approximation.
I have no idea where to even start with this question. Most books don't even mention the Debye...
