Answer :
Final answer:
The density of an atomic nucleus is very high, closer to 6.2 billion cars packed into a one cubic foot box than any other given option. Option A
Explanation:
The density of a typical atomic nucleus is incredibly high, more similar to the scenario given with 6.2 billion cars in a one cubic foot box. In numerical terms, the density of a nucleus is around 2.3 × 1017 kg/m3
. This is vastly denser than any ordinary substance we encounter in our daily lives, including lead, water, or even an aircraft carrier.
The reason for this extraordinary density is due to the fact that atomic nuclei are made of protons and neutrons (each about 2000 times heavier than an electron) packed into a very small space.
