Which is a way that acoustic engineers attempt to limit the destructive interference of reflected sound waves in an auditorium? designing a space with a lower ceiling designing a space with sound-absorbing tiles designing a smaller space designing a larger space

Correct answer is B. Designing a space with sound-absorbing tiles.

In order to limit the destructive interference of reflected sound waves in an auditorium, the acoustic engineers needs to provide sound-absorbing tiles in that area. Due to reflection of sound waves, destructive interference is created in the hall of auditorium. Sound-absorbing tiles have ability to absorb those waves and provide good sound ecosystem to the auditorium room.  

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
