Hello everyone,
I recently tried to find the surface area of a hollow cone (there is no base, like an ice cream cone) using spherical coordinates. With cylindrical coordinates I was able to do this easily using the following integral:
\int \int \frac{R}{h}z \sqrt{\frac{R^{2}}{h^{2}} + 1}...
To my understanding electric potential is the measure of energy per charge.
Now what I don't understand is that the voltage at the point P will be the same if there is a positive charge Q at A and a positive charge Q at B, or if there is a positive charge 2Q at A. I don't get how a test charge...
So are you saying that in real life the wave will reflect off of the atoms in the plane? And that macroscopically the atoms are close enough together to constitute the Bragg plane?
If this is the case, I still do not understand why the waves bounce off of the atoms as if they are in a plane...
I am having trouble understanding what exactly Bragg planes are physically.
I understand how they behave, in that they act like mirrors and reflect matter waves, but what exactly is the wave bouncing off of?
for instance
I can guarantee any physics textbook always has a picture like...
I'm a physics major getting a minor in EE wishing that I had just done Engineering physics from the start. Here's my advise based off of my experience at University of California, San Diego, in the US. The physics major i refer to might be different for Canada physics major because the American...
Instead of asking if a minor in EE is useful, let me ask is it useful to take the following EE classes?
The minor in EE
You take the lower division classes
Intro to Digital Design
Intro to Computer Engineering
Into to Analog Design
Circuits and Systems
Components and Circuits Lab...
Hello everyone,
I am a second year physics major and I have the option of minoring in either EE or taking more math classes.
I don't really care about the titles/pieces of paper, but I would like to know which one is helpful in terms of career and physics skills. I know that taking more math...
You have the initial velocity, and you have the force applied to the mass.
Therefore you can find the acceleration of the mass.
F = ma = -kx (by hooke's law)
The sum of the total force applied is equal to:
F = \int_{0}^{x}-kx\hspace{5} dx
then just divide F by m
find...
Hi everyone,
I am a second year physics undergraduate and I have recently become worried about being employed, even with higher education like a phd. Because of such anxiety I've explored the option of becoming an investment banker on Wallstreet, but I would like to know more information...
Other than being a professor or working in finances/wallstreet, what are the stable jobs that you can get with a background in physics?
That is RELATED TO PHYSICS
I'm really interested in Quantum Computing, and I was pretty sure the best way to get involved in this field was by doing physics, but my dad thinks that by getting a degree/master/PhD in physics is not going to provide a stable job.
I'm currently a second year, and am pretty sure that I can...
I want to show this taylor expansion:
\frac{1}{\sqrt{1+{x}^{2}}} \rightarrow x^2
what I keep getting is something to the x^3 could some one please help me with this simple expansion?
So I know what they are and I've been given some really vague and weak interpretations, but I want to build up my intuition and know more about the specifics of curl and divergence. To my understanding now I know that
curl is similar to a paddle wheel spinning in a direction dependent on the...
