1.A trapeze artist swings in simple harmonic motion with a period of 3.8 s. Calculate the length of the cables supporting the trapeze ? 2. Calculate the period and frequency of a 3.500 m long pendulum at the .
following locations:
a. the North Pole, where ag=9.832 m/s^2?
b. Chicago, where ag=9.803 m/s^2?
c. Jakarta, Indonesia, where a =9.782 m/s^2?

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.

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 − 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).

Awaiver with a period of 0.008 second has a frequency of a. 800hz. b. 80hz. c. 125hz. d. 12.5hz.
