Agas in a cylindrical closed container is adiabatically and quasi-statically expanded from a state a (3 mpa, 2 l) to a state b with volume of 6 l along the path 1.8 pv =constant.
(a) plot the path in the pv plane.
(b) find the amount of work done by the gas and the change in the internal energy of the gas during the process.

While standing outdoors one evening, you are exposed to the following four types of electromagnetic radiation: yellow light from a sodium street lamp, radio waves from an am radio station, radio waves from an fm radio station, and microwaves from an antenna of a communications system. rank these type of waves in terms of increasing photon energy.

Awave with a frequency of 500 hz is traveling at a speed of 100 m/s.what is the wavelength?

Aspectroscope breaks light up into its colors, allowing scientists to analyze light from the solar system and universe. by studying the spectral line patterns, widths, strengths and positions, scientists can determine the speed, position, and of celestial bodies. a) age b) origin c) rotation d) temperature
