1. Families of finite square wells. A particle of mass m has N quantized energy levels in a one-dimensional square well of depth V_0 and width L. N is more than 10
a) Approximately how many bound states does the particle have in a well of the same depth but width 2L?
b) Approximately how many states does the particle have in a width L but depth 2V_0?
c) Approximately how many states does the particle have in a depth 2V_0 and width 2L?
d) How many bound states does the particle have in a well of depth V_0 / 4 and width 2L? In a well of depth 4V_0 and width L/2?
The cylindrical space station, 200 m in diameter rotates in order to give artificial gravity of 3.0 g for the occupants. How much time does it take, in seconds, to complete one revolution.
What magnetic field strength produced by Helmholtz coils
wo resistors R1 and R2 are connected in parallel, and this combination is connected in series with a third resistor R3. what is the equivalent resistance of this combination
A roller coaster is towed up an incline at a steady speed of 0.51m/s by a chain parallel to the surface of the incline. The slope is 2.85 % that means that the elevation increases by 2.85 m for every 100m of horizontal distance.
Compute the most probable distance that a nitrogen molecule will traverse in tissue after 0.5 s if the molecule experiences 1012 collisions/s; assume that the mean free path in air is 10-7 m.
