Answer:
d=3.76 cm
Explanation:
Given that frequency ,f= 4.55 KHz
Speed of sound = 343 m/s
We know that for sound
C= f λ
Where C is the velocity of sound
f is the frequency
λ is the wavelength
So now by putting the values
C= f λ
343= 4550 λ
λ=7.53 cm
We know that for destructive phase the difference in phase is π so the difference in distance will be λ/2.
So distance ,d= λ/2.
d=7.53/2 cm
d=3.76 cm
So they will move at a distance of 3.76 cm to hear minimum intensity of sound.
D is your answer <span>have highly predictable orbits around the sun.

I believe the correct answer from the choices listed above is option B. The scientist most often credited with the idea that matter can have wave-like properties is de Broglie. He <span>related E=mc^2, E=hf and p=mv in order to acquire the de Broglie wavelength, whose formula λ=h/p where h is Planck's constant and p is momentum of the particle.</span>
