Hi all, I need to get a friend a present and as a physicist I really wana get them the 'science toy' kinda thing ... does anybody know the name for the encased photonic pressure experiment in which a fan shape has one black surface and a mirrored surface. When it placed in the sunlight the...

yep i missed the squared out ... thanks for your help :)

Hi, I've been told in a lecture course that the potential used in the virial theorem (for our application) is 3/5 GM/r. This describes the potential for a sphere of radius r, mass M created by bringing infinitly thin shells from infinity to form the next 'layer' of the sphere. I am having...

surendranath.tripod.com/Applets.html .. not so much animations but java applets .. enjoy :D

Hi, please could someone explain the term dispersion relation to me, particularly for the case of a free electron? Thanks Jayse

The photoelectric effect causes the nucleus to recoil

lol! ok its for a nanophysics course and its a method of producing monolayers of atoms. The technique is quite simple, involving a cathode (this is made from the material you wish the monolayer to be made from) and an anode. The cathode is bombared from impacting ions from the anode and atoms...

wow! great answer, thanks Doc :D

Hi, Please could someone explain why it is that the cross section of water emerging from a tap decreases with tap distance ... is it due to air resistance acting to form some kind of aerodynamic shape? any thoughts would be much appreciated!

hey, thanks for the offer but i think I've figured it out now!

What is plasma sputtering?? Hi, I've got a undergrad exam coming up and i can't describe the process of plasma sputtering :cry: , can't find much on the web .. any help would be greatly appreciated

wow! thanks for all the replies, u've cleared that problem up for me :D

Yeh that makes sense, like atomospheric pressure pushing on us ... on the side what would be the difference between a sealed box filled with a balloon ... and the same scenario but this time the balloon is attached to a weight which is being suspended. Would the second box weigh more ... and...

You could try quantum mechanic solutions ... not for the faint hearted though... If you know the number of electrons in Li you have to begin filling shells using the quantum numbers n,l and Ml .. which each have restrictions in their values. You keep filling the electrons in the shells (dont...

Hey, I am not sure if i explained the problem to well... The flask does weigh more (its not a shock ... i hope :S) but the way i intially thought of a solution was to consider the gas to be solid or liquid and imagine the constituents of air neatly sat at the bottom of the flask. But the...
