oh dear. u probably didn't understand the question. after u got the energy for N-N bond. U have to calculate lambda wavelength that too de broglie's. 0.5mv squared is the kinetic energy of the electron. So convert half mv squared to energy momentum

this particularly helps marcia and bonjo
don think of the starting point of the vector. find coordinates of the vector where it ends. Shift origin u have problems with some. Then u can easily find out.
just try it this way. i am sure u will get it. 1st of all they are vectors which are given for which you need to give direction. They are not asking planes. So u need to use square brackets [ and ] not ( and ). Those are for planes. 2nd thing is that u
