Asatellite of mars, called phobos, has an orbital radius of 9.4 ✕ 106 m and a period of 2.8 ✕ 104 s. assuming the orbit is circular, determine the mass of mars. (kg)

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.
