an electron inside spherical metallic particle of volume 10^ -12 metre cube has a kinetic energy about 10 eV. use uncertainty relations to find relative uncertainty in electron velocity .
Q1) consider a stationary nucleus of mass M. show that the minimum energy the photon must have to create an electron-positron pair in the presence of stationary nucleus is 2mc^2(1+ m/M) where m is the rest mass of the electron.
its obivously A!!!!!
In what ways were Lincoln and Johnson similar?
For what reasons did congress oppose the Reconstruction plan to put forward by Andrew Johnson?
What effect do you think Lincolns assassination had no Reconstruction?
oh sorry i forgot.
on the last one its the only one that i didnt get the others im just checking if i got them right.
