Energy is to be stored in a flywheel in the shape of a uniform solid disk with a radius of R = 1.16 m and a mass of 74.0 kg . To prevent structural failure of the flywheel, the maximum allowed radial acceleration of a point on its rim is 3490 m/s2. What is the maximum kinetic energy that can be stored in the flywheel?

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.
