Astronomers estimate that a 2.0 km diameter asteroid collides with the Earth once every million years. The collision could pose
a threat to life on Earth. Assume a spherical asteroid has a mass of 3020 kg for each cubic meter of volume and moves toward the Earth at 13.3 km/s. How much destructive energy could be released when it embeds itself in the earth?

Answer:
The distance between their eye and the ceiling is 33.06 m.
Explanation:
Given that,
The ceiling of a large symphony hall is covered with acoustic tiles which have small holes that are 4.35 mm center to center, D = 4.35 mm
Diameter of the eye of pupil, d = 5.1 mm
Wavelength,
We need to find the distance between their eye and the ceiling. Using Rayleigh criteria, we get the distance as follows :
So, the distance between their eye and the ceiling is 33.06 m.
