2b) for Fermi energy I guess tha ti need to use formula: E=(h^2/2m)(3n/pi) but than i have problem finding n

The mass of sun is determined by measuring the distance of a planet from the sun,the speed of that planet around the sun ,and then using Newtons law of gravity.In the same fashion one can determine the distribution of mass in a galaxy by observing the position adn motion of the stars in that...

I still don't get it I still dotn get it. if hc/lambda=g(mi)B where g=gyromagnetic number B=magnetic field how do i get g and mi ?

thank you thanks to both of you

Radio astronomers have found that besides its optical spectral lines,hydrogen exhibits a radio spectral line at a wavelenght of 21cm.This spectral line arises from the interaction between magnetic moment of the electron and the magnetic moment of the nucleus.The electron is located within the...

I need help solving integral (|X|)^0.5dx is it sam integral as (x)^0.5 except that i will need to integrate from 0 to x since it is absolute value of x Thanks

Show that the symmetric combination of two single particle wavefunction Gab(r1,r2)=Ga(r1)Gb(r2)+Ga(r2)Gb(r1) where G is psi ( i don't have symbol on my computer) displays the exchange symmetry characteristics of bosons (equation G(r1,r2)=G(r2,r1)) Is it possible for two bosons...

For proton and electron of identical energy encounter same potential barrier .For which probability of transmission greatest?

i got it Sorry, I was reading problm 1000 times ,and I didnt realize that they ask for products. Thank you all for help.

I am really stucked with my homework problem.Can anybody help me. The dispersion relation for free relativistic electron waves is w(omega)=(c^2k^2+(m(mass of electron)c^2*2pi/h)^2)^0.5 Obtain expression for the phase velocity Vp and group velocity Vg of these waves and show that...

The probability density at certain points for a particle in a box is zero.Does this imply that the particle cannot move across these points

In what ways does Bohr's model of Hydrogen atom violate the uncertainty principle?
