Wind striking the cups causes the assembly to rotate; a gauge measures the frequency of this rotation and translates the data into wind speed. The length of each arm, as measured Bulb from cup to cup, is 46.5 cm. The friction in the bearings is negligible, so the tangential speed of the cups matches the wind speed fairly closely. Coil Your company makes anemometers and plans to install light bulbs on them for high-wind warnings. The idea is to attach a coil of wire of radius 13.2 cm to one of the arms and use the EMF induced by the magnetic field of the Earth to light the bulb. The bulbs possess 234 2 of internal resistance but need 12.5 W of rms power dissipation to be visible at night. (The resistance of the wire is negligible.) wind Although company management wants this new feature, you have doubts about its practicality. Assuming the magnetic field of the Earth is 0.500 G and is oriented roughly horizontal with the Earth's surface, and…
