Explanation:
Atomic number is the number of proton and atom has. Each element has a specific number of protons, if the number of protons change, then this is a new element.
Mass number is the number of protons and neutrons and atom has.

Data
Number of protons = ?
Atomic number = 20
Then,
atomic number = number of protons = 20
Crates is the correct answer because they create dents that make the bumps of mountains.
Answer:
20.7 billion = 20.7E9 converting to units of 10
20.7E9 km = 20.7E12 m
t = S /v = 20.7E12 m / 3.0E8 m/s = 6.9E4 s = 69000 s
69000 s = 1150 min = 19.2 hrs
