Dale reacted to Demystifier's post in the thread Undergrad Why is gravity a fictitious force? with
Like.
Gravity, of course, is not fictitious because the Riemann curvature is a tensor. But gravity is not the same thing as gravitational... -
Dale replied to the thread Undergrad The effect of a radio wave on an electron.Well, K&K’s book didn’t give you the answer, but they did prepare you with the skills that you needed to discover it, and they did point... -

Yes, let me calculate. We have the position of the electron relative to the origin O : ##x(t) =... -

Dale replied to the thread Undergrad Are the basic axioms of thermodynamics demonstrated experimentally?.Sure, I have seen undergraduate labs on convection. -
Dale replied to the thread Undergrad What is matter?.@Demiurge by way of brief explanation, the QM interpretations sub-forum is for discussing the published interpretations found in the... -
Dale reacted to Ibix's post in the thread High School A question about special relativity with
Like.
It depends what you mean by "slowly". If you mean "if I, at rest on the ground, were to take a series of close-up pictures of the fast... -
Dale reacted to pines-demon's post in the thread Graduate α as angular rigidity of the electron: references? with
Like.
Sure but your original post does not tell me why would that be the case. It is like asking if ##e^2## is related to rotation somehow. -
Dale replied to the thread Undergrad The effect of a radio wave on an electron.Yes. Note that each cycle accelerates and then decelerates the electron. The acceleration portion accelerates from zero to some... -
Dale reacted to Sagittarius A-Star's post in the thread Undergrad The effect of a radio wave on an electron with
Like.
That would be in average the case for electrons in a resistor, but in the OP screenshot, the electron is - according to the problem - in... -

This seems similar to this question you had recently: Consider for simplicity what happens to a body initially at rest that experiences... -
Dale replied to the thread Undergrad The effect of a radio wave on an electron.Look at ##\dot x## instead of ##x##. What is the range of ##\dot x##?
