Answer:
Pauli exclusion principle
Explanation:
No two fermions can have the same set of quantum numbers is called the Pauli exclusion principle. And a electron is a fermion.
There are four basic quantum numbers
Principle quantum number n
the angular momentum quantum number l
magnetic quantum number m_l
and electron spin quantum number m_s
1) The minute travels the circumference of a 4 inches circle is 60 minutes:
Circumference = 2πr = 2π(2in) = 4π in
Time = 60 minutes
2) Constant angular velocity => (4π / 60) = (x / 20) => x = 4π / 3 inches
x = 4.19 inches
Answer: 4.19 inches
