The quantum harmonic oscillator is very important in analyzing the spectra of diatomic molecules. It can also be extended to the analysis of polyatomic molecules. In this problem, you will look at how the energy levels of the harmonic oscillator relate to the spectrum of carbon monoxide. Part A. There is a strong line in the infrared spectrum of carbon monoxide with a wavelength of 4.61μm. What is the energy E of a photon in this line?
Express your answer in joules to three significant figures.
Part B. It can be shown that this line corresponds to a transition between adjacent energy levels in a harmonic oscillator. If this is true, what is the angular frequency Ï of the oscillator? Use â=1.055Ã10â34Jâs.
Express your answer in inverse seconds to three significant figures.

The functioning of an electron transport chain is analogous to a) a slinky toy going down a flight of stairs. b) a canoe going over a waterfall. c) a person climbing a flight of stairs one step at a time. d) a person leaping from the top to the bottom of a flight of stairs in one jump.

Askydiver weighing 140 lb (including equipment) falls vertically downward from an altitude of 19,000 ft and opens the parachute after 18 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity v is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. (a) find the speed of the skydiver when the parachute opens. (b) find the distance fallen before the parachute opens. (c) what is the limiting velocity vl after the parachute opens? (d) determine how long the sky diver is in the air after the parachute opens. (e) plot the graph of velocity versus time from the beginning of the fall until the skydiver reaches the ground.

World class speed skaters can skate a 3,000-m course in about 4 minutes.what is their average speed for this course? a. 12.5 m/sb. 1.33 m/sc. 1.25 m/sd. 13.3 m/s
