Two in-phase loudspeakers, a and b, are separated by 3.20 m. a listener is stationed at c, which is 2.40 m in front of speaker b. both speakers are playing identical 214-hz tones, and the speed of sound is 343 m/s. does the listener hear a loud sound, or no sound?

If anyone who can me with this hw? i would really appreciate it

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.

Write a hypothesis about the effect of increasing resistance on the current in the circuit. use theformat and be sure to answer the lesson question. “how do changes in voltage or resistance affect current in an electric circuit? ”
