Rest mass energy of an electron is 0.51 MeV. If this electron is moving with a velocity 0.8 c (where c is velocity of light in vacuum), then kinetic energy of the electron should be.
0.28 MeV
0.34 MeV
0.39 MeV
0.46 MeV
the patial vapour pressure of any volatile componants of a solution is equal to the vapour pressure of the pure components multiplied by its mole fraction in the solution
