Answer:
Explanation:
time to diffuse x cm is given by the relation
t = X² /2D
D = 5.7 x 10⁻⁷
t = X² / 2 x 5.7 x 10⁻⁷ = X² x 10⁷ / 11.4 s
X = 10 pm = 10 x 10⁻¹² m = 10 x 10⁻¹⁰ cm = 10⁻⁹ cm
t =( 10 ⁻⁹)² x 10⁷ / 11.4 = 10⁻¹¹ / 11.4 = 8.77 x 10⁻¹³ s
Answer:XY X +Y

<span>This is because the theory is supported by the <span>Doppler</span> shift effect phenomenon observed in the universe. The Doppler shift effect shows the galaxies are continually moving away from each other , meaning they were once close together, and probably a singularity in the beginning as explicated in Big Bang Theory, and that a force/energy is driving them further apart.</span>
