I NEED HELP PLEEEASEEE DUE TODAY Take some time to research a utility plant. If there is one in your area, you may even visit it. Otherwise, look up a type of plant that produces energy - such as a nuclear power plant, a hydroelectric plant, or a coal-burning plant. Find out what energy resources are brought into the plant. Then find out what energy and what “waste” is produced by the plant. Describe how the two Laws of Thermodynamics apply to what you find out in your research. Be thorough. You will be using the information you gather to engage in a debate with your class about thermodynamics.

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.

Unpolarized light whose intensity is 1.19 w/ is incident on a polarizer. (a) what is the intensity of the light leaving the polarizer? (b) if the analyzer is set at an angle of = 41.0∘ with respect to the polarizer, what is the intensity of the light that reaches the photocell?

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?
