A certain power plant puts out 550 MW of electric power. Estimate the heat discharged per second, assuming that the plant has an efficiency of 38%.

SolutionStep 1 of 4 a. Telephone signals are often transmitted over long distances by microwaves. What is the frequency of microwave radiation with a wavelength of 3.0 cmFor the microwaves used in telephone transmission,Given data The wavelength of the microwave is, =3 cm 2 2Using 1 cm=10 m =3× 10 m Microwaves speed will be equal to speed of light as they are EM waves, v = c = 3× 10 m/sTo find, The frequency of the microwave, f =
