Well I thought it was very interesting. I'm always learning something when I watch your videos. Thanks a lot for putting them here. 👍

Having trouble with scale values, help. dv/dx = (50-10)/(200-0) =40/200 = 1/5; so a= v*dv/dx = v/5; at x=0, v=10 so a = 10/5 = 2, at x=200, v=50, so a = 50/5 = 10. Your graph has 18. ???

Oh wow

Hello, I'm having a hard time accepting that both velocity and acceleration can both be linear at the same time when plotted as a function of distance x, and at the same time be both continuous in the case of velocity and discontinuous in the case of acceleration at the point x = 200. Myself (and many others probably) and mostly versed in the time domain when talking about distance, velocity and acceleration problems, and I think it would make for a very satisfying connection if you were able to convert this specific example to the time domain and explain such a conversion in more detail (I guess I'm specifically asking about comparing v(t) with v(x) and a(t) with a(x) if possible).

❤❤❤❤❤. Thanks a lot.

Nice little problem

wow

Damn

thank you sir

👏

If it were a stranger shape instead of a circle, would you take the line integral for dq such that dq=lambda ds where ds would parameterize x and y

Do you have to make 🔺X = 0 at the end of the calculations or can you start by assigning its value to zero?

what a beautiful law

I am an advanced level student from sri lanka and this is really helpful. if you ever thought of making fortune just come to sri lanka and start doing tuition classes

Nice video explain the AC transmission line . You didn’t account for inductive and capacitive losses and things like power factor correction . Those also cause a loss in power lines not just resistance

sir how to calculate force applied by ball on ground in this case?

thank you my high school teacher keeps yapping and i still dont know what he is talking about

Mr. Michel, where did that 80 come from? I can't catch it!

Good Day sir! What reference book do you use for this discussion? I have watched your video discussions about RL circuit and I Aced my test yesterday. Thank you very much

What is rpr?

Thank so much

Hmmm... These numbers appear to be approximations. Only 2 decimal places are used for Mercury's orbital period. l would like to see the values using 100 decimal places for Mercury's orbital period.

The electric field of multiple charges is the vector sum of the individual electric field of each of the individual charges

Dr. van Biezen, I have a favor to ask: On one of your past videos (several years ago), you showed a long list of all the physical constants that one ought to memorize in the course of learning physics and astronomy. I have spent a fair amount of time trying to find it, but I would value ($) it very much if you could point me to it. Thank-you for all the great videos !!!

Why do teachers love trick questions like this? I came here to learn, not a "got'ca!" moment.

Total waste of time, I found the solution in 2 secs without calculation

what the f* does welcome to electron line mean

The formula is in reverse order

Mr. Professor lambada is a constant i.e. change of charge with the distance? (linear)

Thank you, sir!❤

Wtf is 100newtons? Who uses that measurement?

Hi I have a question. Will the final answer include c = pai/4? I am assuming no, because C = tanc = 1? Is that correct?

You have astounding dedication 🙏

Thanx!😊

This one looks familiar......in the integral list from Fourier Series videos? 😊

so helpful! rthank you for making these videos

I can understand English just a little bit so it so hard for me if it isn't have subtitles 😢😢

Clarification at 1:30 - Gamma is never less than 1. For v going from 0 to the speed of light C, Gamma goes from 1 to infinity. Any other values of v are not possible in the physical world.

Hi, Professor. I hope you are doing well. Today, I had Physics exam and during discussion, we couldn't bring resolution idea for the following question. Thus, I am forwarding the question to you to make a video on it or just reply to my message. Thanks. The time required to fill a bucket with water from a certain garden hose is 30 s. If you cover part of the hose’s nozzle with your thumb so that the speed of the water leaving the nozzle doubles, how long does it take to fill the bucket? A. 7.5 sec B. 15 sec C. 60 sec D. 30 sec

Hi Michel, If temperature increases, the resistance of flow will decrease, but at 2:20 in the video, you have stated it in the opposite manner, which is confusing.

H

thank you very much big THANK YOU clear explaination, btw anyone 2024?

Can l use flamink left hand rule for this sir

Your videos are not visible

ty so much sir!!

As the integral in the general solution initally contains a constant , would 'nt the final answer contain two constants ?

sir could you please explain how rth is 10 ohm , by short circuting all sources well have 2 ohm parallel to 6 ohm then series with 4 ohm ? , i'm confused with this part sir

thank u so much for this needed this
