The resistance of the coil of a pivoted-coil galvanometer is 8.37 Ω, and a current of 2.94×10−2 A causes it to deflect full scale. We want to convert this galvanometer to an ammeter reading 21.0 A full scale. The only shunt available has a resistance of 3.00×10−2 Ω.

Question is unclear.found on internet original question: "what should isla write in the areas marked a, b, and c? x-rays, both, radio waves)a: has a longer wavelengthb: travels at the same speedc: has a higher frequencyanswers: a) has a longer wavelength  --> radio waves. in fact, radio waves have wavelength in the range of the meters, while x-rays have wavelengths of a few nanometers.b) travel at the same speed --> both. both radio waves and x-rays are electromagnetic waves, which travel (in vacuum) at the speed of light, c.c) has a higher frequency --> x-rays. in fact, the shorter the wavelength, the higher the frequency. since radio waves have longer wavelength, they have lower frequency, while x-rays frequencies are higher.

The electromagnetic radiation examples  are: gamma rays, x-rays, radio waves, microwaves, visible light, infrared light, ultraviolet rays.their speed is lightspeed:   186282.397  miles per second.
