1. ### A Books/Resources related to the thermal model for particle production

I can only find papers relating to how they've used the model but nothing about the model.
2. ### I Resistance of Platinum decreases with an increase in temperature ?

Basic Procedure The experiment basically involves finding the null point on the Carey Foster's bridge with the PRT as the unknown resistance and using a Resistance box as the variable resistance. In the above diagram, P and Q are 2 fixed resistors of equal resistances. For obtaining the first...
3. ### I Newton's Rings Experiment

No, I'm pretty sure I haven't. I can send in a couple of my readings if you want to.
4. ### I Newton's Rings Experiment

I did consider that but I'm pretty sure I haven't and even if there was, since we're plotting D2 vs n, the error would either be of 100 or 0.01 because we're squaring D.
5. ### I Newton's Rings Experiment

When monochromatic light is incident on a plano convex lens(as shown in the picture), these dark rings are produced which are observed with the help of a travelling microscope. The procedure requires us to measure the diameter of each ring (We need to measure the diameter of at least 10...
6. ### I Project on Electricity & Magnetism(Topic Suggestions needed)

So I have taken up this course on Electricity and Magnetism and we need to prepare a project as in not very broad as such but for example, attempting to solve a problem or something that is related to the subject but off the course. I'd like to involve computation too in some form or the other...
7. ### Programs What and Where do I apply?

Thank you so much for opening my eyes and I'll do try for what you said.
8. ### Melde's Experiment

Homework Statement Why working formula for transverse and longitudinal arrangement in melde experiment different in Melde's experiment ? Homework Equations None. The corresponding equations are all derived from the same fact. The Attempt at a Solution So, I have understood that the tuning...
9. ### Twin spring system with a mass in between (X and Y direction)

I have a really silly question, but : 1. Are we assuming the mass to be a point mass? 2. Are the springs allowed to "turn" or "twist" ?
10. ### Twin spring system with a mass in between (X and Y direction)

Okay so I'm just an undergrad but like how about you place the ball at an arbitrary position, lets say (x0, y0) with the spring being streched, and then compute the net force in terms of the angles(which could be further expressed in terms of x and y coordinates of the ball) and then have two...
11. ### Programs What and Where do I apply?

I realised this like 2 weeks ago and it's been troubling me really hard because I don't see any practical applications to physics without engineering.
12. ### Programs What and Where do I apply?

So I'm an undergrad student from India pursuing physics, I'm currently in my first year and I'm really confused as to what I should do. I mean, I like physics, especially the computational aspect of it, but I don't know if I'll continue physics after three years. Summer's gonna start soon and I...
13. ### Admissions Applying with high percentile/low scores

Ohh abroad I see. You sure your parents fine with it right ? (Speaking from experience) And for what course btw ?
14. ### Admissions Applying with high percentile/low scores

Dude you'll easily get in, but I ned an idea as to where exactly do you wanna apply ? Cos as far as uni's are concerned (excl. engineering institutes) the best ones open (or stay open) after the results come out.
15. ### Sources of errors in a spectrometer experiment

The curve of angle of deviation vs angle of incidence
16. ### Sources of errors in a spectrometer experiment

yea the i-d curve :cool:
17. ### Sources of errors in a spectrometer experiment

How do I move the thread ? And this was more like a general question rather than a homework question but okay.
18. ### Sources of errors in a spectrometer experiment

[Note from mentor: this lacks the homework template because it was originally posted in a non-homework forum.] I know this seems like a very dumb question but every other error I think of has been covered in precautions and the only errors I can think of are dumb ones. Help ! I had to plot the...
19. ### B How do I improve my proof writing style?

Thank you so much everyone ! :) I'll see to all of them !
20. ### B How do I improve my proof writing style?

Any other suggestions ?
21. ### B How do I improve my proof writing style?

So I've taken this Linear Algebra class as an elective. So there's stuff that is so obvious and logically/analytically easy to prove but I honestly don't understand how to prove them using the standard way. So what should I do about this ? And I really like linear algebra so I don't want to mess...
22. ### B Whats the principle behind Schuster Focusing?

I know its something related to the asymmentry in the i-d curve but its still not clear.
23. ### Error When Deriving the Rocket Equation

How do you say that ve is negative ? ve is the velocity that I measure(of the ejected mass) if I'm sitting on the rocket, so in order to actually state if its positive/negative, you need to tell me where your origin is. Well, It'll be ten times easier to understand if you just do it normally, I...
24. ### Error When Deriving the Rocket Equation

Relative velocity of the mass wrt to the rocket is ##v_{mass}(inertial frame) - v_{rocket}(inertial frame)## Right ? ⇒ ##v_e = v_{mass} - v## As a result, ##v_{mass} = v_e + v## ∴ ##p_{dm} = (dm)v_{mass}## ⇒ ##p_{dm} = (dm)(v_e + v)## Hope you got it ! Feel free to reply :)
25. ### Error When Deriving the Rocket Equation

Oh, I wrote my solution w.r.t. the diagram. If its the relative velocity, then momentum of the ejected mass would be dm(##v + v_e##) ##v_e = v_{exhaust} - v## Because, ##v_e## is the velocity of the ejected mass w.r.t. the rocket. And i guess, then the cancellation takes place.
26. ### Fizeau's Experiment (Speed of light)

Okay just a teeny doubt, how do you define an eclipse ? I mean I used n in order to maintain the series but like what would be its physical significance ?
27. ### Fizeau's Experiment (Speed of light)

Thank you so much ! After generalising, I'm getting $$\frac {4LNf} {2n-1}$$ Although I'm yet to confirm is this is the answer, but this is what I get. Again, thank you so much !
28. ### Fizeau's Experiment (Speed of light)

How does it become 3/(2N) for n=2 ? Could you explain ?
29. ### Conceptual problem in average/instantaneous velocity

Did they integrate it over time though ?
30. ### Error When Deriving the Rocket Equation

This is where it went wrong. You're in an inertial frame, so the momentum of the exhaust ejected is ve)dm. I don't know why you took the relative velocity in the original equation but it will present itself in the later steps. (when you calculate the change in momentum) ∴ mv = (m - dm)(v + dv) -...
