Oscillator. consider a h1271 molecule (force constant 313.8 n m1, equilibrium bond length 161 pm) in its vibrational ground state. (a) plot the probability density function (in pm1) as a function of the bond length (in pm). (b) calculate the probability of finding the molecule with its bond length 157 pm or shorter. [you will need the error function, look it up. use a computer to evaluate it (e. g. wolfram alpha website)]

Scientists and engineers design new technologies to solve problems. often, a new technological design will contain a flaw. which of the following is true about such a flaw? a. it should be studied so that the design can be fixed or a new design can be proposed. b. it means that the problem being investigated cannot be solved. c. it means that the people who proposed the design should not be scientists or engineers. d. it makes the technological design useless.
