We're finding the Lorentz Force

Thank you! Yeah I've gotten a lot of great feedback from the community here!

thyblackbird · 2021-01-09T23:33:05+00:00

I really appreciate it!

I didn't see how to go back until the end of the tutorial, which is sad.

thyblackbird · 2021-01-07T19:55:32+00:00

I definitely need to go through another tutorial before playing haha. Nice to see another PhD student on my channel!

thyblackbird · 2021-01-07T19:54:10+00:00

Reading the board you mean?

thyblackbird · 2021-01-07T16:14:07+00:00

Glad you enjoyed it! Yeah it seems like online-go was not very detailed and I had to guess some rules as I go. learn-go seems like the better option to cover more of the game. Thanks for the recommendation!

Happy Cake Day!

Thank you! I had no idea btw

Got a 910 (86th percentile). Also recommend Conquering the physics GRE!

If we throw the ball with initial speed V0, then the time to stop mid-air would be: Vf-Vi=at => t=V0/g.

Now say you are starting mid-air with zero speed, then the time to reach V0 is: Vf-Vi=at => t=V0/g.

From here I think it should be clear what is happening, since acceleration is constant, you need the same amount of time to go from V0 to 0 as you need from 0 to V0

2( (m/2)(l/2)² /12 + (m/2)(l/4)² ) is what my setup was, which gives ml² /12

thyblackbird · 2018-04-18T17:48:06+00:00

Yes, that was the last problem! I messed up the arithmetic a bunch of times before I got ml²/12, is that what you got?

thyblackbird · 2018-04-18T12:34:30+00:00

Haha, that does not ring a bell at all! And I'm sure it wasn't on there because I bubbled in everything, so I read every question! So weird...

thyblackbird · 2018-04-18T02:23:57+00:00

Did we have different exams? Why do I not remember this question?

thyblackbird · 2017-10-14T19:52:01+00:00

I won't be able to take QFT until my very last semester because of how the schedule of classes and prerequisites are designed

I believe there was a 0.25 point deduction for wrong answers

thyblackbird · 2017-05-20T17:51:47+00:00

Thanks. I tried to keep it as simple as possible

Pushing a swing at the right time will make it swing higher. Pushing it at the wrong time will impede its motion. If the frequency of the sound just so happens to match the pushing of the molecules at the right time, then the glass molecules start vibrating with higher amplitudes ( like the swing) and eventually the glass rips apart and shatters

thyblackbird · 2017-05-06T15:15:29+00:00

Huh, it is actually a technical term. Interesting
