Unformatted text preview: higher energies a particle can have? (b) Is 30 eV an allowed energy? (c) Is 32 eV an allowed energy? (d) Given the box length is 0.434 nm, what is the mass of the particle? (e) What do you think the particle is? 8. What is the uncertainty in velocity of an electron trapped in a 1.00 nm length box? Repeat for a proton. 9. An electron has a speed of 10.0 km/s. How much time is needed to measure its kinetic energy with an uncertainty of 0.100 percent? How far will it travel in this time?...
