SSteve4Physics reacted to berkeman's post in the thread Which material will stop magnetic attraction? with
Agree.
Can you post a link to the online question? Obviously any magnetic shielding effect would require a ferrous material. -
SSteve4Physics replied to the thread Which material will stop magnetic attraction?.IMO the answer-key is wrong and the correct answer is d - the steel sheet. Steel* has a high magnetic permeability. A large steel sheet...

SSteve4Physics reacted to kuruman's post in the thread Finding the acceleration of a block on an inclined plane with friction with Agree.
In addition to @Steve4Physics's comments: 1. Please note that we prefer that you post your work in ##\LaTeX## which makes the equations...

Like.
After reading the following article, your understanding to the Doppler effect will be much more clear. You may find this article by... -
SSteve4Physics replied to the thread Questions about a parallel plate capacitor apparatus for lab experiments.@DDesulgon, you might find the following link useful - it describes an experiment with the sort of capacitor similar to the one you...

SSteve4Physics replied to the thread Find the acceleration of a block (some sort of double Atwood machine?).Yes. Agree 100%. In case there's any confusion, I certainly wasn't (in Post #10) promoting the OP's (Post #1) approach. But in Post...
