because I put that it's was right
Answer:
The value is 
Explanation:
From the question we are told that
The distance of the speaker from the second speaker to the east is
The distance of the speaker from the listener to the south is 
Generally given that if the speaker move in any direction, their sound become louder , it then mean that the position of the listener of minimum sound (i.e a position of minima ) ,
Generally the path difference of the sound produce by both speaker at a position of minima is mathematically represented as
Generally considering the orientation of the speakers and applying Pythagoras theorem we see that distance from the second speaker to the listener is mathematically represented as

=> 
=> 
Generally the path difference between the two speaker with respect to the listener is
=>
=> 
So
=> 
Answer:
A. There is a localization of positive charge near the door handle.
Explanation:
- When on a cold morning a person wearing cotton/ polyester cloth walking on the carpet moves toward his car then due to friction between the feet and the carpet there are transfer of electrons from the carpet to our feet, and since our body is a good conductor of electricity the charges spread throughout on the surface of or body.
- When the person brings his hands close to the neutral conducting door of the car it gets induced with equal intensity of opposite charge to our hands thus having a concentration of positive charges near to the hand on the car's door is developed as a result of polarization within the conductor.
