Consider a wavefunction which is proportional to sin [(27/a)x] and extends over the range -2 < x< (and is equal to zero everywhere else). a) normalize the above wavefunction. b) sketch the probability density of the above wavefunction c) what is the probability of finding the above particle at some (anywhere in the range 0 x< 2)?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
