The mass of an electron is 9.11×10−31 kg. if the de broglie wavelength for an electron in a hydrogen atom is 3.31×10−10 m, how fast is the electron moving relative to the speed of light? the speed of light is 3.00×108 m/s. express your answer numerically as a percent. view available hint(s)

Ans: The electron is moving at 0.732% relative to speed of light.

Explanation:
According to the de Broglie relationship:


So,

h = Planck's constant = 6.626 * 10^-34 Js
m = mass of electron = 9.11 * 10^-31 kg
λ = wavelength = 3.31 * 10^-10 m


m/s

Since the electron is moving relative to the speed of light, therefore the ratio is(in %):

% = % = 0.732%

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
