etermine the magnitude of the electric field produced, by a dipole of length L2= 1.65m at a frequency F2= 30360000Hz and a distance of r2=217m at an angle ø= 30, the radiated power is 12 KW

What is the frequency of an EM wave that has a wavelength of 1667.58 m?  Round your answer to two decimal places.

A sound speaker is rated at a voltage of P = 120.0 V and a current of Iurrenmt = 8.00 A Electrical power consumption is P = IV , where the units are: [W] = [A] [V] . To test the speaker, a signal of a sine wave is applied to the speaker. Assuming that the sound wave moves as a spherical wave and that all of the energy applied to the speaker is converted to sound energy, how far from the speaker is the intensity equal to I = 3.73 W/m ? Express your answer in m. Hint: remember, the intensity of a wave is I =
