Evaluate the vibrational partition function for nh3 at 850. k where the vibrational frequencies are 950., 1627.5 (doubly degenerate), 3335, and 3414 cm−1 (doubly degenerate).

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

An incident ray through the focal point of a spherical mirror will: reflect through the center of curvature. reflect back through the focal point. reflect parallel to the principle axis. reflect the same direction as the incident ray.
