Is the soeed of an electron relativistic?

AI Thread Summary
The discussion focuses on determining whether the speed of an electron in a hydrogen atom is relativistic, given its circular orbit around a proton at a radius of 0.5 x 10^-10 m. The participant expresses uncertainty about the relevant equations and how to approach the problem, particularly regarding centripetal acceleration and velocity. They eventually indicate that they have solved the problem. The key takeaway is that an electron's speed in this context needs to be compared to the speed of light to assess its relativistic nature. The conclusion emphasizes the importance of understanding both classical and relativistic physics in such calculations.

Homework Statement


Determine the speed of an electron in a hydrogen atom (radius .5 * 10^-10 m) and state if it is relativistic. (Treat the electron as through it were in a circular orbit around the proton.) (Given that .1c and greater is relativistic)

Homework Equations


not sure...
L=L0 (1-v^2/c^2)^1/2
a=v^2/r
?

The Attempt at a Solution


I don't really know where to start. I assume the fact that the electron has a centripetal acceleration and velocity comes into play somehow.

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
