Amicrophone records sound produced from two speakers in a room with no other sound sources. if the intensity of one of the sound waves at a given location is 0.055 w/m^2 and if the microphone receives a minimum intensity of 0.004 w/m^2 when both speakers are active what is a possible value for the intensity of the other source at the microphone's location? (a) need more info to solve. (b) 0.088 w/m^2 (c) 0.051 w/m^2 (d) 0.048 w/m^2

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
