November 2003 Question 4 C :- attachment
When the wavelength is reduced, this means that each photon has more energy now since this means higher frequency by E=hf formula.
the intensity of the electrons is to be kept constant.... look , if electrons come with high energy, they should come in lower amount to keep the intensity constant.... and if they come with lower energy, they should come in high numbers to keep the intensity constant.... hope you can understand....
i)1- mean = average is 4.8 + 6 / 2 = 5.4Hey all, can somebody help me?

Question 4, can you explain all of part (b) to me?
Was explained to XPFMember, Thermal energy is required to increase the electric potential of the particles by breaking some intermolecular forces.
2*10^-7 is the force betwee n the wires carrying curent of 1 A and distance b/W them is 1 m................hey guys... i'm doing electromagnetic questions, and there's this equation 'B= 2x10-7 x I/x'
Where the heck is this equation from? :O
and what is 2x10-7 supposed to be
Unless someone answers it, I will be solving 2010 tomorrow.http://www.xtremepapers.com/community/threads/a2-physics-post-your-doubts-here.13317/page-11
Anyone plz solve my question on this page
Thanks

P.S:- 0.05 percent silver = 5 g out of 100g
0.95 percent gold = 95 g out of 100g
