Jenna is standing in the middle of two identical loudspeakers that are 3 m apart and face each other. The speakers are driven in phase by the same oscillator at a frequency of 873 Hz. The speed of sound in the room is 345 m/s. Find the shortest distance in centimeters Jenna can walk toward either speaker in order to hear a minimum of sound. Please give your answers with 1 decimal place.

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
