Much better now - I feel silly for copying those off my assignment sheet without noticing the mistakes! Cheers!

Homework Statement The problem is your typical N-body simulation, implemented using Python and Numpy. The implementation specifically calls for using the Euler-Cromer method. For this particular case I used the Sun and the first 4 planets of the solar system. Essentially the problem is I'm...

Doc Al, did anyone tell you how awesome you are? Thanks for the support! :D

Yes, that's what I was thinking as well - it's the velocity *just* as it is leaving the pipe. Sorry for all the questions lately, but this was in my first university physics exam and I'm a bit scared about it to be honest! Never actually properly had physics before - quite a challenge but I'm...

Also, why does the angle of the tap not matter?

Where do forces come in however?

Ah, how silly of me...I neglected to use ##v_0 = \sqrt{2gh}##! Thanks DocAl : - )

Homework Statement A cubic wine box of dimensional length ##h## has a small tap at an angle at the bottom. When the box is full and is lying on a horizontal plane with the tap open, the wine comes out with a speed ##v_0##. i) What is the speed of the wine if the box is half empty? (Neglect...

Ah, how silly of me! Looked at the result you forwarded as well - got it now. Thank you so much and all the best for the new year!

In which case ##T' = T## - thus ##T## is independent of ##\alpha##? What is wrong in my reasoning that results in me obtaining ##T \propto \cfrac{1}{\alpha}##?

Thank you! I'm not quite sure what you mean exactly. With some reasoning I could have also said that since ##v \propto \alpha##, then ##r \propto \alpha##. It thus follows that ##T \propto \cfrac{1}{\alpha}##.

I am given the solution to the first part of the problem, however not the second part - would appreciate for someone to double check my work! Cheers. 1. Homework Statement If a scale model of the solar system is made using materials of the same respective average density as the sun and...

Thanks Doc Al! All the best for the new year.

I'm trying to solve this problem, however I'm unsure if my reasoning is correct - I do agree with the answer, but something seems wrong to me in my reasoning. 1. Homework Statement A rod is on a frictionless surface, and is defined by the length L and mass M. It is hit on one end by a piece...
