An athlete exerts a tension of 6.00×102n on one end of a horizontal rope that has length 50.0 m and mass 2.50 kg. the other end is tied to a post. if she wiggles the rope with period 0.575 s and amplitude 3.00 cm, what is the angular frequency of the oscillation?

9.98 kg of r-134a at 300 kpa fills a rigid container whose volume is 14 l. determine the temperature and total enthalpy in the container. the container is now heated until the pressure is 600 kpa. determine the temperature and total enthalpy when the heating is completed. use data from the steam tables.
