Before Posting This , I spent nearly an entire day googling the problem of virtual particles and the conservation of energy , but it only got me more confused :confused:
Let's review this problem from the beginning :
Due to Heisenberg's uncertainty relation between time and energy \Delta t...
hi
i have a problem with the the proof of faulhaber's formula given http://planetmath.org/encyclopedia/ProofOfFaulhabersFormula.html"
how is \left(\sum_{k=0}^{\infty}\frac{n^{k+1}}{k+1}.\frac{x^k}{k!}\right)\left(\sum_{l=0}^{\infty}B_{l}\frac{x^l}{l!}\right) equals...
I Heard That the gamma function explains the strong nuclear force .
\Gamma \left( z \right) = \int\limits_0^\infty {t^{z - 1} } e^{ - t} dt
How does it explain the Force?
Thanks
Hi Everyone ,
Beckman44 , I Understand That you need to produce pulses as fast as possible , So you need to use an astable circuit like the one in the attachments .
There are Some Equations Control The Properties of the pulses and they are :
( The frequency Equation )
\[
f =...
Hi , Everyone
I'm learning how to read datasheets , amd i have a question about this .
In the datasheet of the transistor BC238 , in the Absolute Maximum Ratings the Ic = 10mA
Does That mean that i can't get an Ic output = 1000mA .
Thanks .
hi everyone
the integral is :
\[
I = \int\limits_0^1 {\int\limits_0^x {\int\limits_0^y {ydzdydx} } }
\]
I'm not sure about the answer , but i think it'll be
\[
\frac{{x^3 }}{3}
\]
am i right ?
thanks
Hi
assume that a Cylinder with radius \[
R
\] , proper mass \[
M_0
\] and height \[
h
\] which is rotating at a constant angular speed \[
\omega
\]
In order to calculate the relativistic mass we use the proper mass element to calculate the relativistic mass element , so :
\[
dM =...
Hi
I have a simple question
in GR we can claculate the gravitational acceleration of the black hole with the Equation :
\[
a = \frac{{GM}}{{r^2 \sqrt {1 - \frac{{r_s }}{r}} }}
\]
now , the acceleration of a mass which falls into the black hole at the event horizon (when
\[
r = r_s...
