Solution Problem #33 Binary Stars

Solution Problem #33 Binary Stars

[jfgobin]

I have almost the same solution, I used a_1=G.m_2/d^2=r_1.w^2 to find w, and ultimately T=109 years. Slight variation on the same theme.

By the way, what is the best way to submit a solution with a proper layout, until YouTube supports Latex?

Lastly, thank you very much for the time you spend making these exercises and solutions. I used to love physics during my studies and I have not done much of it since I graduated. It is a real delight to be able to use that part of my brains again.

Wow !!! Your passion for teaching is unparallel

[taanmostafa]

Thank you professor, keep going and ask us more physics problem.
God bless you

Thanks sir, your student from Bharat 🇮🇳, preparing for IIT JEE 2022.

Sorry, had no time. Next one I hope.

Do you have any electrical ones in stock ? I would like that

Hi Walter. I have a question. If gravity bends light, why is it that the entire earth doesn't light up 24 hours a day from the light emitted by the sun.

I've been trying to make sense of it after watching Einstein's experience which proved that light does bend when exposed to gravity.

Where to post solutions ?
Are only ans sufficient or solutions should be posted

Professor when we should analyse motion wrt non-inertia frame and how it can simplify our problems.

Professor❤ Do the stars change their place or following small Ellipse over time?? *I found that they follow small Ellipse or Round path* Professor❤ I found this thing with that Red star which I have been watching since December (that Red Star - About which we have talked many times).

Sir why, when a body is moving under a Central force potential in a circular orbit then total energy=V(eff)....why no K.E?? I want to say basically both radial and transverse k.E =0??

Please be always alive walter!!!
The world needs the people like you!! Not the 99% of people.

Sir now i am studying in class 11 and want your help.Can u suggest me the important chapter of class 11 that will required for nuclear physics because i am planning my career in nuclear physics

[guntassaran]

My answer was right. I solved using Kepler’s Third Law

Hey prof. I want to ask you about your clip about pulley that what is MR means? and can you tell me how to study physics well thank you

[ShadowZZZ]

I wonder how exactly newton came up with the equation for graviational attraction as well as how people calculated the gravitational constant

[chakshupunj]

Sir, I know total Energy in a body due to Gravity is -GMm/2R. If an object falls from a point P (at R) to a point at p (at R') and if R'<R the energy at p is more negative then at P. So energy decreases from P to p by an amount ∆E (say). I want to know in which form ∆E get converted?

nice shirt :-) very good teacher. Take care

[scotchbeef]

i dont know much about physics but i love you and your shirt.

Is there any potential difference across an ideal inductor?
I guess there should not be as electric field inside it is zero, but according to Faraday's law there is a induced voltage across it. Please help me connect these two contradicting statements.

I thought in binary systems we are meant to use m1v1=m2v2 through cons of momentum?
