I'll get my pic up soon, but for now this is my old one. It's kinda dark too in my room on that pic. I'll get you guys a nice one by tomorrow. I promise!
Also I am kinda new since I registered a long time ago and really haven't had time to come back. But now since I'm working for an...
Doughnut Calculus!
Hey guys, I need help with a somewhat big Calculus IV problem. We are reviewing double and triple integrals in polar coordinates. So here is my problem:
Work out the mass, 2nd moment, and radius of gyration for a doughnut shaped yoyo about both x and y axes...
I know...
i think you should look at that equation as so...
∫f(x)g'(x)dx = f(x)g(x)-∫g(x)f'(x)dx
for example a simple integral:
Find ∫x sinx dx.
∫x sinxdx= f(x)g(x)-∫g(x)f'(x)dx
= x(-cosx)-∫(-cosx)dx
= -x cosx + ∫cosx dx...
YEAH!
thanks man. So i guess my thought was slightly off, considering i didnt think about absorbtion or scattering. Thanks again man. Finally the crazy thought i had in class is quenched. In fact i think ill look up the other ways that a neutron could be stopped also, they seem interesting...
Hey guys, posted this in HW help, but its actually just a thought i had in chem class.
I was wondering if light or heavy elements would be better at stopping slow moving neutrons? And how come? By heavy and light, i mean mass.
Heres what i think. I thought a heavy element would have a...
hey m8, do you mean the circle is spinnning horizontally over his head or vertically next to him? i found out horizontally i think, but if its vertically spinning next to him let me know. i got like 4.47 Newtons, but that's if the ball is spinning above his head horizontally. lots of...
Hey guys,
I was wondering if light or heavy elements would be better at stopping slow moving neutrons? And how come? By heavy and light, i mean mass.
I always thought a heavy element would have a better chance of stopping particles because they have a high probability of smacking the...
