Flu, U is the voltage of the battery

12 years ago

Are these the formulas for 2nd problem?

12 years ago

Yeah, only c) worked for me

12 years ago

Do you know 1st c) and d) ?? And 3rd problem??

12 years ago

Period (P) = 1/F

12 years ago

anyone got the 2nd answer???

12 years ago

6_2A= -t_0*x 6_2B= -t_0*(x^2-L^2)/(8*pi*G_0*R^4) 6_2C= -L^2*t_0/(8*pi*G_0*R^4) 6_2D= 5*t_0*L/(4*pi*R^3) 6_3= 8*psi*G*I_o/(L^2) i need 6_1B

12 years ago

b) 0

12 years ago

No, do you have any idea for others problems?

12 years ago

I got 4th problem

kyle and ss01 can you please tell me how to solve the 1st problem?

12 years ago

I didn't get you, can you explain it properly how to do the 1st problem

12 years ago

Well, I don't know how to differentiate, can you explain it to me.

Can you tell me how to calculate distance of the particle to the origin at time, speed of the particle and the smaller angle? I got the acceleration. Thanks

12 years ago

Thanks. Did you get Stone On Roof Find Distance problem?

12 years ago

What is the distance here?

11 years ago

Yes, this method is not working

What about the remaining parts??

11 years ago

I couldn't understand part c. In wolframalpha, what do we have to enter as the order of the taylor series and the point?

I need help for airliner and double well potential ( K=? T=? )

11 years ago

And also for sliding down the dome's 2nd part

11 years ago

I didn't get the 2nd part, If I plug in 50*10*cos(30) , i get the answer wrong.

ss01, can you please tell me a,b,c parts?

11 years ago

@ mouse, my x_0 is 2, lambda is 5, a=4, b=60 and mass is 80kgs. Please tell me the value of K, i tried to solve it by your method, but i got it wrong.

11 years ago

Yes i got x0, but i didn;t get k, can you please tell me how to calculate k for those values?

11 years ago

Thats what I am not getting! My x0 is 2, so F(x)= F₀-k(x-2), when i type this in taylor series calculator of wolframalpha, i get a huge equation!

11 years ago

Please help me mouse

11 years ago

@ KS, can you please tell me how you got the solution for Double Well potential? I am not getting the value for k.

11 years ago

Thanks a lot mouse and KS, Did anyone get the airliner and the pendulum problem?

11 years ago

ss01, can you please tell me the solution for the airliner problem?

11 years ago

Thanks a lot mouse, I could solve the pendulum problem. But, in the mass spring problem, I got x1=0.5714 , so mod(x2-x1) should also be equal to x1, correct? But when i typed in the value, it showed that x1 was correct but mod(x2-x1) was wrong :( Also, I...

11 years ago

@ mouse, I read the airliner prob properly, I solved it but got it wrong. I am confused in the equations. Their equation is F(t)=-F0+Bt , whereas ours is F(t)=-F0+(t/ts-1)*F1. What is B? I have only 1 try left now :(

11 years ago

@ mouse, in the airliner's problem, what units do we have to keep? I converted kN to kg and tonnes to kg as well.

11 years ago

I think i have got how to work for t12, let me try first.

11 years ago

Yes yes, even I got the same result, but solved it a little differently

11 years ago

Yes, try it yourself, I got a green tick!
