A conductive wire has a resistance of 36 ohms at 32 ° C centigrade and 63 ohm at 23 ° C. Calculate the temperature coefficient and the resistance it presents if the temperature increases by 100 ° C compared to the initial one.

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.
