Un niño juega con una pelota de tenis de 125 gramos de masa y la hace girar en un círculo vertical. La longitud de la cuerda es de 90,0 cm. El niño la hace girar lo suficientemente rápido como para mantenerla en movimiento formando un círculo completo, lo que da como resultado una aceleración centrípeta de 5 g en el punto más bajo. Calcula la VELOCIDAD mínima necesaria en el punto más alto para...

1.6 Photoelectron Spectroscopy
มุมมอง 293 หลายเดือนก่อน
The binding energy value in a PES diagram represents the energy required to remove the electrons from a particular subshell. Coulomb’s law tells us that the electrons that are located closer to the nucleus should have a stronger attractive force to the nucleus. Therefore the core electrons that are located closer to the nucleus should have a higher binding energy (i.e., require more energy to r...

Hi, I think there is supposed to be an asymptote for the graph as t increases. You can also derive acceleration by taking the derivative of the velocity formula.
pov having a teacher who doesnt teach and you have to look up frq to not get a B in class
@@balltomessi8515 we've all been there 🤣
thanks goat u gon be the new khan academy
are u single? u look cute <3
I hope you won't dissapear like a 4 dimension boy 😢
You really helped me out with your ap chemistry videos THANK YOU😭
I'm so glad!
Where can i find similar questions?
I would recommend the textbook Physics for Scientists and Engineers: A Strategic Approach with Modern Physicsby Randall D. Knight (Professor Emeritus)
Thank you so much for this! I was unable to understand the scoring guidelines. The video was very helpful
Saving me 🙏
Awesome work
why was newtons not identified in the question?
Wouldn’t the graph go into negatives at the middle point because it changes from positive velocity to negative velocity?
¿Que?
sometimes a video with soo less views is really helpful, thank you soo much!!
The friction force was actually 130.36N that's why your answer should've been -1043J!! Thank you for the explanation
thank you SO much. my first ap physics c is tomorrow and this me understand things a lot better.
thank u king
you're clutch my homie
So cool thx
just let me use my damn power rule 😭😭
Reduce the size of your webcam, it is too big😂
Nice video. You should do a tutorial on the Seifert Van Kampen theorem! Nice work.
is it not 9^2 /7 since its 9^3/9^1 = 9^2
I guess my question is im confused when you go from taking the constant out of the integral
@@pabloooooooooooo6621 just for the sake of simplicity it looks cleaner in my opinion
yes when he crossed out terms and brought the constant outside the integral he forgot to include 9^2
was this prerecorded cuz the damn test is literally 7 motnhs away lmao
I think for sake of completion you should still substitute back in what theta is in terms of x.
i still don’t understand how you thought of this in the first place, like how does it makes sense?
This is a substitution method used by mathematicians that do calculus that I had learned earlier, if you have any further questions I can clear up any confusion on a particular subject!
@@kinetic.tutoring Thanks for the solution, just 1 issue, while factoring out 9 cube and nine you only left a 9 instead of 9 square
hwllo
really appreciate the help 🙏🙏🙏
thank you i was really wondering the answer to ap physics c ap exam set 1 question 2 🙏🏻🙏🏻
super helpful thank you
needed this 🙏
For part B the line should be vertically placed on x axis
Been waiting for this one🔥
In the last part you forgot the sin(theta) when you plugged your stuff into the kinematic equation
My IB Sl physics mind cannot comprehend this 😥
What really bugged me was I couldn't figure out why there is no friction acting on the ball at point B. Can you explain? (Btw Thanks for making a video)
Not sure... I think if it's rolling wihtout slipping there has got to be a static frictional force. I think he just made a mistake
@@perryo1063 There was no static force on CB's official solution either.
How was your prom night young gentleman?
Solve my marriage issues please
No Cap!
Electric fields bro, pls make this!
Sorry, could you please elaborate a little further???
@@kinetic.tutoring Certainly bro, I have a few advanced problems specific to this section I need you to tackle and solve more,thks in advance!
what about FRQ 3?
expect a response video within the next 24 hours!
@@kinetic.tutoring thank you so much!!
what did you score on your latest test?
I was also wondering the same thing, surely this intelligent young man aced it!
W video🔥
ion think she wants me anymore bro
focus on urself king
i don’t get it
I apologize if I couldn't explain this concept clearly enough, where did you seem to get lost?
Do you know enough astrophysics to do videos on it? Or rocket dynamics such as escape velocity of a planet?
I have not studied astrophysics yet, but if you had any questions do not hesitate to send them over to my work email @kinetictutoringemail@gmail.com, and I will take a look at the problems to see if it is within my capabilities!
Thanks for making this video and answering my question!
How would one find the differential equation of motion in the first place?
stay posted, will post a response within the next 24 hours my friend
@@kinetic.tutoringgreat, looking forward to learning.
Wow i learned sm
thx teach😊
