This assignment covers the remaining ma- terial that will be in the first exam. 001 10.0 points You are caught in a radar trap and hope to show that the speed measured by the radar gun is in error due to the uncertainty prin- ciple. If you assume that the uncertainty in your position is large, say about 10 m, and that the car has a mass of 2150 kg, what is the uncertainty in the velocity? 1. 1 10 33 m 2. 1 10- 39 m / s 3. 5 . 10- 38 m / s 4. 2 . 5 10- 39 m / s 5. 4 10 38 m / s 002 10.0 points In a one-dimensional particle in a box, for n = 7, how many WHOLE wavelengths equals the size of the box? 1. 7 2. 14 3. 3.5 4. 6 003 10.0 points An electron is confined in a 1-dimensional box 3 nm long. Calculate the energy required for it to move from the n = 8 to the n = 9 energy level. 1. 2 . 133 10- 19 J 2. 2 . 133 10- 14 J 3. 6 . 694 10- 21 J 4. 1 . 717 10- 14 J 5. 1 . 138 10- 19 J 6. 3 . 414 10- 28 J 7. 5 . 238 10- 19 J 004 10.0 points A quantum mechanical particle in a box in its ground state is most likely to be found 1. in the middle of the box. 2. is equally likely to be found at all positions in the box. 3. is equally likely to be found at all positions except the very center of the box....
