Great explanation!

Sorry, when we calculated the tension, why we considered tension from one uniform post, we have 2 of them?

Hello, thank you very much for your help! There is one typo on 4:07 as f2=(v+v0)/v as observer moves

I am sorry, but I think the formula of k might be wrong. I assume it must be upside down.

Thank you!

Hi, how could you set the Pasco capstone so that it shows all values in a table for several runs?

You are life saver, appreciate it thanks man

👍👍

Sir please explain this. On a vertical disk a rod of length L is suspended on that disk at radius r and mass is attached to that rod end and vertical disk starts to rotate clockwise so how to calculate centrifugal force on that rod and mass attached to it. Neglect rod mass and how much mass is require on the rod to keep it stay vertically downward at different rpm.

Tmax = N I A B sin90 then we choose N as 1 then put this one to calculate T again?

Please solve 6, 9, 12, 19

Well explained. Ty

Thank you for this video, I subscribed, you take time to explain and that's why I subscribed 🙏

Nice explanation brother

Thank you

Thank you so much

Thank you so much! I was struggling with understanding the continuous charge distribution

better than Khan Academy

Mr. Askar, so can we always generalize cases like this (where plate dimensions are given and limited) to an infinite plane? Since the formula you used is applied to infinite plane examples in textbook. Thank you

Should the mass be given?

In the second part, it seems you missed '2' in the formula. The formula is Vf^2 = Vi^2 + 2a(delta)x, isn't it?

Don't we have to find a position instead of velocity?

no voice?

I think here in part b, we should use the formula Vf=Vi+at. Then we get Vf=Vi-gt=10.0167-9.8*1.5=-4.68. Am I right?

I have a question. Why total T(vector) equals the sum of the Ty and Tx vectors? And how we can solve this problem if there will be another angle, like 120, etc?
