Yeah, thank you for response, already got the answer.

I am getting ready for exams and I have encountered this problem on the exam paper: In AC circuit there is a condensator and a inductive coil, At first XL=XC, how does the relation change when the frequency doubles? The answer says XL=4XC Can someone explain me how they come to this conclusion...

Now I see that I made a mistake, because I used a spinor with a given theta, so I would get the same result.

Maybe I haven't made it clear enough, but in the first case angle theta is known and in the second one the spin is calculated by averaging all possible theta's Thank you for your reply :)

Homework Statement After beta- decay electron and antineutrino comes out, electron is moving along z axis and it is moving with velocity v. It's spinor is ## \mid\chi\rangle=A\left(\frac{\sqrt{1+\frac{v}{c}}\sin\frac{\theta}{2}}{\sqrt{1-\frac{v}{c}}\cos\frac{\theta}{2}}\right) ## where A is...

I get that the answer is https://imgur.com/OdTtc5D Is it correct?

Thank you very much!

How accurate is stellarium in time? Does it add something more to VSOP87 or it just uses it ?

It seems that I was doing it wrong. How could I change the position of Orions belt projection on Earth to the place of pyramids and then tighten it to match Giza pyramids?

Thank you very much

In stellarium there are equatorial coordinates and galactical coordinates. I was using galactical coordinates. How should I convert equatorial coordinates to geographic?

Hello, I am doing an astrophysics project about Orion belt constelation and the pyramids of Giza. I am interested in the myth that the three pyramids is an exact copy of Orion belt. How should I convert galactical latitude/longtitude to linear/geographical coordinates so I could compare the...
