Make sure to answer all questions that have not yet been answered Last/First Name (print): PHYS 1440-Section Username ID (XXX9999) WS Analysis A: 1. The voltage difference between the AA and AAA batteries should be quite small. What then might be the difference between them? AXA 2. If we have a resistor labeled brown-black-green-gold, what is the average expected value? Why is it necessary to measure the resistor? Analysis B: 3. What is the average voltage in step 8 of part B? And, when a DC offset is applied, what is the average voltage then? 4. What two values were obtained when calculating the root-mean-square voltage in step 13? How do they compare to the measured value? Which one is correct, and why? (Hint: with an offset Vrms = /DC +

The particle in a two-dimensional well is a useful model for the motion of electrons around the indole ring (3), the conjugated cycle found in the side chain of tryptophan. we may regard indole as a rectangle with sides of length 280 pm and 450 pm, with 10 electrons in the conjugated p system. as in case study 9.1, we assume that in the ground state of the molecule each quantized level is occupied by two electrons. (a) calculate the energy of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels. 9.27 electrons around the porphine ring (4), the conjugated macrocycle that forms the structural basis of the heme group and the chlorophylls. we may treat the group as a circular ring of radius 440 pm, with 20 electrons in the conjugated system moving along the perimeter of the ring. as in exercise 9.26, assume that in the ground state of the molecule quantized each level is occupied by two electrons. (a) calculate the energy and angular momentum of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels.

Greg drew a diagram to compare two of the fundamental forces. which labels belong in the areas marked x, y and z? gravitational force electromagnetic force x. attractive y repulsive z: infinite range x: infinite range y attractive z. repulsive x. always attractive y: infinite range z: attractive or repulsive x. attractive or repulsive y infinite range z: always attractive
