A 1.0-kg ball has a position uncertainty of 0.20 m. What is its minimum momentum uncertainty?
Answer to relevant QuestionsAn electron and a proton each have a momentum of 3.28470 x 10-30 kg ∙ m/s ± 10-30 kg ∙ m/s. (a) The minimum uncertainty in the position of the electron compared with that of the proton will be (1) larger, (2) the same, ...What is the minimum uncertainty in the position of a 0.50-kg ball that is known to have a speed uncertainty of 3.0 x 10-28 m/s? An electron is accelerated from rest through a potential difference of 100 V. What is the de Broglie wave-length of the electron? An electron is accelerated from rest through a potential difference so that its de Broglie wavelength is 0.010 nm. What is the potential difference? Nuclide A has a half-life that is one-third that of nuclide B. The type A sample starts with twice the number of undecayed nuclei as in the sample of type B. Compare the initial sample activities expressed as a ratio of the ...
