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
Answer:


Explanation:
Let the mass of the other car is "m" and its kinetic energy is

now the mass of the first car is two and half times and its kinetic energy is half that of other car
so we will have



now speed of both cars is increased by value of 9 m/s
so now we will have same kinetic energy for both cars





so speed of first car is


Answer:
No, the distance from the last stop to the school and the time it takes to travel that distance are required.
