Hmm, i just rethink again, maybe i should first use Amperes law to find the relationship of magnetic field inside the wire, then use superposition of the de-magnetic field due to the hole and add them up together.# Just a guess, is the magnetic field still a circle inside the wire? (assuming no...

Homework Statement A cable with given diameter D1 is given, a small hole with diameter D2 is drilled on it. The axis of them are parallel and the distance between the axis are given as r. There is a uniform steady current density flowing through it. How to calculate the magnetic field at the...

How much Helium will be produce by fusion process in fusion power generator (assuming they are operational)? Will it be a lot? Because this might lead to increase concentration in atmosphere after a lot of year of running like CO2. High concentration of helium can be dangerous because helium is...

This is a bit tricky. I need to read some books for reference from the library but all the related books has been borrowed and will only due back after the submission deadline. What should i do?

Thats pretty interesting. Cool. I will try to look at that in further details as well. Thanks.

Is fusion power definitely going to be our future primary source of energy?

I have to write up an essay for my second year undergraduate physics. The essay has to be high in physics contents. Have asked quite a lot of friends, but most of them seems to be doing black holes or something about astronomy. As for myself, i planned to go for future energy but seems...

Is there any treatment to cure those victim who got radiation overdose?

Oh rite, i see. Thanks for helps! Edit: oh, btw, is there any functions that can't be parameterized?

Is there a specific method to parameterised a function of scalar and vector? I was reading through this website but then, can't understand how it read taht parameterised steps. Any guide? (http://www.math.umn.edu/~nykamp/m2374/readings/stokesex/index.html under double check...

hmm, doesn't seems to work that well. Coz i been washing dishes in warm water as well but it is still there. Edit: Anyway, once it really stick onto it, does it really matter anymore?

I see. Thats so true! Should be more wary next time. But how can u remove them once they stick onto ur broken blisters?

I just got a broken blister, but was then later I was trying to put some flour on the the fish. TO my amaze, it made a cover on top of the injured place and something like a plaster cover. So i m wondering, do flour helps in preventing tissue under skin expose to air, and maybe helps prevent...

Hmm, not sure about that, but in my case i can play LAN games with my friends as long as they are in the same college. I can't play with them even they are in the same university network but different colleges. Well, for portforwarding, u could try www.portforward.com .
